Finding the best ignition coils for acura tl is less about choosing the longest parts list and more about confirming the engine, year, connector, and replacement numbers. A complete six-coil kit can simplify a tune-up, but only if its fitment matches your specific TL.
My first choice is ENA UF242 Set of 6 Ignition Coils. Its bolt-on, three-terminal, 12-volt design is intended as a direct replacement, making it a practical option when several original coils are aging at the same time.
My second choice is Pindex UF242 Six-Pack Ignition Coils and 4503 Iridium Spark Plugs. That makes the package appealing for a full ignition refresh, although buyers should carefully confirm the plug and vehicle fit before ordering.
My third choice is CarBole UF242 Six-Piece Ignition Coil and Iridium Plug Set. It also includes six coils and six iridium spark plugs, giving it strong value for a buyer who needs both parts at once.
The comparison below separates the kits by fitment, included parts, warranty information, and buyer suitability. After the product details, the guide explains compatibility checks, installation preparation, troubleshooting, maintenance, common mistakes, and when a complete six-coil replacement makes sense.
Best Ignition Coils for Acura Tl
I selected these products by prioritizing Acura TL year and engine coverage, matching replacement numbers such as UF242 and 30520-P8E-A01, and considering useful installation details. Customer-feedback evidence was also weighed where available, while brand variety helps show the differences between budget kits, bundled tune-up packages, and a DENSO-branded option.

ENA UF242 Set of 6 Ignition Coils
ENA’s six-coil package is the strongest all-around match in this group because its listed Acura coverage spans the 1999–2008 TL 3.2L and the 2007–2008 TL 3.5L. That broad range is useful for owners who want one complete replacement set rather than buying individual coils as misfires appear. The kit also lists compatibility with the Acura CL and RL, plus several Honda V6 applications.
The coils use a three-terminal, bolt-on format with valve-cover mounting and a 12-volt electrical specification. In normal use, those details point toward a straightforward replacement process, but they do not eliminate the need to compare the old coil, connector, and engine application before installation. Listed reference numbers include UF242, C1221, 30520P8EA01, and several related numbers, giving buyers multiple ways to cross-check the part.
A complete six-pack is particularly sensible when the vehicle has high mileage, several stored misfire codes, or an ignition service already underway. Replacing only one failed coil can be less expensive immediately, but another original unit may fail later. ENA includes a 12-month warranty, and the product carries a 4.5-star rating from 1,757 customer ratings in the supplied data. That is considerably more feedback than the other aftermarket kits here.
Pros
- Broad Acura TL 3.2L and 3.5L fitment coverage.
- Complete set of six with multiple cross-reference numbers.
- Bolt-on, three-terminal design and 12-month warranty.
- Strong customer-feedback volume and 4.5-star rating.
Cons
- Fitment varies by year, engine, and related vehicle submodel.
- Does not include replacement spark plugs.
My Opinion
ENA is my best balanced pick for an Acura TL owner who wants a complete coil set, broad listed compatibility, and meaningful customer-feedback history. Confirm the exact engine and connector before ordering, especially on transition-year vehicles.
Pindex UF242 Six-Pack Ignition Coils and 4503 Iridium Spark Plugs
Pindex takes a different approach by combining six UF242 ignition coils with six 7098 double-iridium spark plugs. For a TL that is already due for plugs, this can reduce the effort of sourcing two separate parts. The spark plugs are described with an iridium center electrode and a platinum disc welded to the back of the ground electrode, details intended to support durability and consistent ignition.
The coil side uses a three-pin design and lists several interchangeable numbers, including 30520P8EA01, UF242, C1221, UF400, C242, and GN10168. The supplied fitment covers the 1999–2008 Acura TL 3.2L and the 2007–2008 TL 3.5L, along with Acura CL and RL applications. It also lists Honda, Saturn Vue, Pilot, and Ridgeline applications, so the buyer should avoid assuming that every vehicle in the listing uses the same configuration.
This package suits someone performing a more complete ignition service rather than replacing a single failed coil. The trade-off is that bundled plugs are only an advantage when the included specification matches the engine and the buyer actually needs them. The product has a 4.5-star rating from 110 customer ratings and includes a 12-month warranty, but its feedback pool is much smaller than ENA’s.
Pros
- Includes six UF242 coils and six 7098 iridium spark plugs.
- Useful cross-reference list for fitment checking.
- Listed coverage includes Acura TL 3.2L and 3.5L applications.
- 12-month warranty and 4.5-star customer rating.
Cons
- Extra plugs are unnecessary if the existing plugs are still fresh.
- Only 110 customer ratings are supplied, limiting long-term feedback depth.
My Opinion
Pindex is my preferred alternative for a buyer planning coils and spark plugs together. It offers good package value, but exact engine and plug compatibility matter more here because the kit contains two ignition components that must both be correct.
CarBole UF242 Six-Piece Ignition Coil and Iridium Plug Set
CarBole’s package includes six UF242 coils and six iridium spark plugs, so it targets the same complete ignition-service situation as Pindex. Its listed Acura fitment covers the 1999–2008 TL 3.2L and 2007–2008 TL 3.5L, as well as the 2001–2003 CL 3.2L and 2005–2008 RL 3.5L. That makes it relevant to several Honda-family V6 applications, but the broad listing is also a reason to use the vehicle selector and part numbers carefully.
The coils are described as direct plug-in replacements with three-pin connectors. CarBole also states that the units undergo thermal shock, humidity, and vibration testing, and that the silicone rubber boots are intended to withstand high heat. These details are useful because a coil boot must insulate the connection near the spark plug, although supplied claims should not be treated as proof that every vehicle will experience identical service life.
For a beginner, the all-in-one format can make a scheduled tune-up easier: remove the old coils and plugs, inspect the wells, and install the matching new components. The downside is that a full kit may be more than needed when only one coil has failed and the plugs were recently replaced. CarBole has a 4.6-star rating from 78 customer ratings in the supplied data, the highest average among these products, though the sample is relatively small.
Pros
- Six coils and six iridium plugs in one package.
- Direct plug-in, three-pin coil design.
- High-heat silicone boots and stated environmental testing.
- 4.6-star customer rating in the supplied data.
Cons
- Small customer-feedback sample compared with the ENA kit.
- Complete kit may be unnecessary for a single-coil repair.
My Opinion
CarBole is a sensible third choice when a full ignition refresh is the goal and its part numbers match the TL. I would choose it for the bundled plugs and stated boot construction, while keeping expectations realistic about aftermarket consistency and limited feedback volume.
FOMIUZY UF242 Six-Coil Pack
FOMIUZY combines six UF242/C511-style ignition coils with six 4503 iridium spark plugs. Its stated Acura coverage includes the 1999–2008 TL 3.2L and 2007–2008 TL 3.5L, along with selected Accord, Odyssey, CL, and RL applications. The package is therefore aimed at a complete V6 ignition refresh rather than a single replacement.
The listing emphasizes enhanced materials, resistance to aging and high voltage, and a long service life. Those claims describe the intended role of the components, but they do not replace basic fitment verification or inspection of the vehicle’s existing wiring and plug wells. The listed replacement numbers—UF242, C511, 4503, GN10168, C1221, 30520P8FA01, 30520-P8E-A01, and 30520RCAA02—give the buyer several comparison points.
A notable advantage is the stated lifetime warranty. That can be valuable for an owner who plans to keep the TL for a long time, provided the warranty process and replacement conditions are acceptable at the time of purchase. The product has a 4.4-star rating from 46 customer ratings. Because its feedback base is smaller and its claims are broad, I would place more weight on confirmed compatibility than on the warranty alone.
Pros
- Six ignition coils and six 4503 iridium spark plugs.
- Broad listed Acura V6 coverage and useful OE references.
- Stated lifetime warranty.
- Suitable for a complete ignition refresh.
Cons
- Smaller customer-feedback sample than the leading kit.
- Warranty terms should be confirmed before relying on them.
My Opinion
FOMIUZY is worth considering when a lifetime warranty and bundled plugs are priorities. It ranks below the first three because the supplied customer-feedback base is smaller, so precise year, engine, and connector matching should guide the purchase.
Sixity Auto DENSO Six-Pack Direct Ignition Coils
Sixity Auto’s package stands apart because it supplies six genuine DENSO direct ignition coils rather than a bundled coil-and-spark-plug kit. The listed fitment covers Acura TL 3.2L and 3.5L V6 models from 1999 through 2008. For an owner who already has suitable spark plugs or wants to choose plugs separately, that narrower package can be an advantage.
The product includes original packaging and hardware and is described as a direct replacement. DENSO is also the named brand of the parts, which may appeal to buyers who prefer a recognized component manufacturer over an unbranded or less familiar aftermarket kit. Still, “direct replacement” does not mean every TL configuration is identical, so the Amazon Confirmed Fit process and the vehicle identification details remain important.
The main limitation is the small amount of supplied customer-feedback evidence: a 4.2-star rating from only three ratings. That does not establish poor quality, but it provides less useful ownership history than the higher-volume ENA listing. This kit also does not include spark plugs, so it may cost more to complete a tune-up if the plugs are due. On the other hand, avoiding unwanted extras can be economical when the plug service was recently completed.
Pros
- Genuine DENSO-branded direct ignition coils.
- Six-piece set for listed 1999–2008 Acura TL V6 applications.
- Includes original packaging and hardware.
- Good fit for buyers who want coils only.
Cons
- Only three customer ratings are supplied.
- Does not include spark plugs.
- Fitment must still be confirmed for the exact TL.
My Opinion
Sixity Auto DENSO is the specialist choice for someone who values the named DENSO brand and does not need bundled plugs. Its limited feedback and higher potential total tune-up cost keep it fifth in this comparison, but it may be the right targeted purchase for a coil-only repair.
How I Selected These Best Ignition Coils for Acura Tl
The selection starts with application relevance: every option lists the Acura TL, and the leading products identify the 3.2L and 3.5L V6 ranges that matter most here. I then compared connector style, replacement numbers, quantity, included spark plugs, warranty information, brand identity, and customer-feedback volume. A kit with many compatible-looking numbers is not automatically better; it must still match the exact vehicle.
Check the TL’s model year and engine before comparing price or package size. A six-piece kit is useful only when all six coils use the correct connector and mounting arrangement.
Customer ratings helped separate the options, but rating count matters too. ENA has substantially more supplied feedback than the other aftermarket choices, while Sixity Auto’s DENSO listing has only three ratings. I treated warranty statements as useful ownership support rather than proof of performance.
A complete coil-and-plug kit is convenient for scheduled maintenance, while a coil-only package can be the better choice when the spark plugs were replaced recently.
How to Choose the Best Ignition Coils for Acura Tl
Start with the vehicle, not the advertised kit size. Enter the TL in the retailer’s fitment tool, compare the engine and year against the listing, and then verify the connector and replacement number. The best choice depends on whether you need one coil, six coils, or a complete coil-and-plug service.
- Match the exact TL year and V6 displacement.
- Compare numbers such as UF242, C1221, and 30520-P8E-A01.
- Confirm whether the package includes six spark plugs.
- Consider warranty length and customer-feedback volume.
- Inspect the old connector and coil shape before installation.
Match the Engine and Model Year
The supplied listings cover overlapping but not identical applications. The 3.2L TL appears across the 1999–2008 range in several listings, while the 3.5L TL is specifically shown for 2007–2008. Do not use a nearby Acura model as a substitute for confirming the TL. Trim, production changes, and regional differences can affect the correct part.
Compare the Replacement Numbers
UF242 and C1221 appear repeatedly in the aftermarket listings, while 30520P8EA01, 30520-P8F-A01, and 30520RCAA02 are additional references. These numbers are helpful cross-checks, but a number printed in a listing should be compared with the vehicle selector and the physical connector. If the numbers conflict, pause the order rather than guessing.
Decide Between Coils Only and a Full Kit
Six coils make sense when multiple cylinders show ignition problems, the vehicle has substantial mileage, or the owner is already replacing all plugs. A coil-only set avoids paying for spark plugs that are not needed. Bundled plugs are convenient, but they should be the correct specification for the exact engine and not simply treated as free extras.
Understanding Acura TL Ignition Coil Symptoms
A failing coil can contribute to a rough idle, hesitation, reduced power, or a check-engine light, but those symptoms can also come from spark plugs, fuel delivery, vacuum leaks, wiring, or engine problems. A cylinder-specific misfire code is a useful clue, not automatic proof that the coil is the cause.
Pay attention to whether the problem appears during acceleration, at idle, or only after the engine warms up. Intermittent symptoms may be harder to isolate. Before ordering six coils, inspect the plug condition and look for oil or moisture in the plug well. Those findings can point to a separate issue that would affect a new coil.
Preparing for Installation
Gather the correct replacement coils, spark plugs if included or required, basic hand tools, and a way to keep dirt out of the plug wells. Work on a cool engine and disconnect the negative battery cable if the vehicle service procedure calls for it. Keep each removed component organized so the original connector and mounting positions are easy to compare.
Inspect Before Installing
Compare the replacement coil with the old unit. Check the connector shape, terminal count, boot length, mounting point, and overall profile. Do not force a plug into a connector that does not align naturally. A mismatch is a reason to stop and recheck the order, not a problem to solve with pressure or modification.
Replace Plugs Carefully
If the kit includes iridium plugs, verify that the plug number matches the vehicle application before installation. Keep the plug threads clean, avoid dropping the plug, and follow the vehicle manufacturer’s tightening guidance. Over-tightening can damage threads, while an insufficiently tightened plug may not seal correctly.
Basic Installation and First Start
Remove the engine covers or access components as necessary, disconnect each coil connector, remove the retaining bolt, and lift the coil straight out. If replacing plugs, remove them only after clearing debris from the area. Install each new coil fully over the plug, secure the fastener without excessive force, and reconnect the electrical plug until it is properly seated.
After reassembly, start the engine and allow it to idle while checking for an obvious rough run, warning light, or loose connection. A short, careful drive can reveal whether the original symptom remains. If the check-engine light flashes or the engine runs badly, stop driving and diagnose the problem rather than continuing under load.
How to Make Replacement Coils Last Longer
Coils operate in a hot, vibrating environment, so surrounding conditions matter. Keep the engine area clean enough that debris does not fall into the plug wells during service. Address oil or water contamination promptly, since moisture and fluid can interfere with the boot and plug connection.
- Use the correct spark plug type and installation torque.
- Keep connectors dry and fully latched.
- Do not pull on wiring when removing a coil.
- Repair oil leaks that reach the plug wells.
- Investigate repeated misfires instead of repeatedly replacing coils.
Diagnosing a Misfire After Installation
If a misfire remains after new coils are installed, first confirm that every connector is seated and every coil is fully positioned. Check for a damaged wire, loose ground, incorrectly installed plug, or a plug well containing oil or moisture. A scan tool can identify whether the misfire remains on the same cylinder or has moved.
Do not assume the new part is the only possible cause. A fuel injector, vacuum leak, compression issue, or sensor fault can create symptoms that resemble ignition failure. If the problem follows one coil when components are carefully exchanged for diagnostic purposes, that is stronger evidence than replacing parts at random; follow the vehicle’s service guidance and avoid unnecessary swapping.
Common Mistakes When Buying Acura TL Coils
Most avoidable problems happen before installation. Buyers often see “V6,” “UF242,” or a broad Honda-family fitment and skip the exact TL year and engine check. Others replace one part without investigating why it failed or buy a plug bundle that does not match their maintenance plan.
- Ordering by engine size alone without checking the year.
- Confusing Acura TL, CL, and RL fitment.
- Ignoring the connector or terminal count.
- Assuming a high rating guarantees exact fitment.
- Forcing a coil or plug into place.
- Replacing coils without checking for oil or moisture.
Never modify a connector to make an incompatible ignition coil fit. Return to the part number, vehicle selector, and physical comparison instead.
When Should You Replace All Six Coils?
Replacing all six is reasonable when several coils are failing, the car has accumulated substantial mileage, or access to the rear bank makes repeated repairs inconvenient. It can also pair logically with a scheduled spark-plug replacement. However, a single isolated failure does not always require six new coils, especially when the remaining units are known to be healthy and the replacement set would strain the budget.
Use the vehicle’s symptoms, diagnostic information, service history, and the condition of the removed parts to make the decision. A complete set offers consistency and convenience, but it should not replace proper diagnosis.
Warranty and Ownership Considerations
The supplied kits differ in warranty support. ENA and Pindex list 12-month warranties, while FOMIUZY states a lifetime warranty. The Sixity Auto listing emphasizes genuine DENSO parts, original packaging, and hardware but does not provide a warranty length in the supplied information. Before purchase, save the order details and check the seller’s current warranty process.
A warranty is most useful when the buyer can document the vehicle fitment, installation, and failure. It is also worth considering whether a replacement is shipped quickly and whether the buyer must cover return shipping. These practical details can matter more than a headline warranty period during an unexpected breakdown.
FAQS About Best Ignition Coils for Acura Tl
What ignition coil part number is commonly listed for an Acura TL?
UF242 and C1221 are common references in the supplied Acura TL coil listings. Other numbers include 30520P8EA01, 30520-P8F-A01, GN10168, and C242. Always compare the reference with the exact TL year, engine, connector, and retailer fitment result.
Do all six Acura TL ignition coils need to be replaced together?
No. A single confirmed failed coil can be replaced individually, but a six-piece set is practical when multiple coils are failing, the vehicle has high mileage, or spark plugs are already being replaced.
Are bundled spark plugs useful with Acura TL ignition coils?
They can be useful during a complete ignition service, especially when the existing plugs are due. Confirm that the included 7098 or 4503 plugs match the exact engine before installing them.
Can Acura TL 3.2L and 3.5L coils be treated as identical?
Not automatically. Several listings cover both engines, but the correct part still depends on model year, connector, and application. Use the vehicle fitment tool and compare the original coil before ordering.
What should I check if a new Acura TL coil does not fix a misfire?
Check connector seating, plug installation, oil or moisture in the plug well, wiring, fuel delivery, vacuum leaks, and compression. A misfire code identifies a cylinder but does not prove that the coil is the only fault.
Final Thoughts
For most buyers, ENA Set of 6 Ignition Coil Pack 3.0L 3.2L 3.5L is the strongest overall choice for the best ignition coils for acura tl because of its coverage, complete six-pack, warranty, and substantial customer-feedback history. Pindex 6 Pack UF242 Ignition Coil 4503 Double Iridium Spark is the best alternative for a coil-and-plug service, while CarBole UF242 Ignition Coils and Iridium Spark Plug Set offers another well-equipped package. Confirm the exact year, engine, connector, and part number before placing the order.
