Replacing all four ignition coils on a Honda Accord typically costs between roughly $235 and $730, depending on engine type, parts choices (OEM vs aftermarket), and labor rates. If you only need to replace a single faulty coil, the price is substantially lower.
What influences the price
The total cost to replace ignition coils on a Honda Accord varies with the engine model, whether the coils are coil-on-plug units or separate packs, and where you have the work done. Accords from different years use coil-on-plug designs for each cylinder, so replacing multiple coils requires purchasing four individual coils and the associated labor. Regional labor rates and diagnostic charges also play a role.
Parts costs
Here is a typical breakdown of part costs for replacing all four ignition coils. The numbers assume a four-cylinder Accord with coil-on-plug ignition systems common in recent model years.
- OEM (Honda-equipment) ignition coils: commonly $80–$120 per coil
- Aftermarket ignition coils (compatible brands): commonly $40–$90 per coil
- Spark plugs (optional if you’re already in there): $8–$40 each depending on brand and type
- Coil boots/seals and other small consumables: $5–$15 per boot (if replacement is recommended)
In total, you can expect part costs for four coils to range from about $160–$480 for aftermarket parts and roughly $320–$480 for OEM parts, with additional costs if you replace spark plugs at the same time.
Choosing between OEM and aftermarket
OEM parts typically come with a higher price but offer factory-grade compatibility and warranty support. Aftermarket coils can save money and often perform well, but quality varies by brand. If your Accord is still under warranty, or you’re seeking maximum reliability, OEM coils are a safer bet; for cost-conscious repairs, reputable aftermarket coils are common alternatives.
Labor costs
Labor costs depend on local shop rates and the time needed to access and replace all four coils. The job is generally straightforward on a four-cylinder Accord, but exact time can vary by model year and service practices.
- Typical shop hourly rate: $75–$150
- Estimated time to replace all four coils: about 1–2 hours in most cases
- Diagnostic fees: some shops waive or apply toward the bill if you proceed with the repair
Overall labor for four-coil replacement commonly falls in the $75–$300 range, depending on the site and how the car is accessed.
What can affect labor time
Labor can extend if the engine layout requires extra disassembly, if access is restricted, or if the shop finds related issues (such as worn spark plugs or damaged boots) that need addressing beforehand.
Cost scenarios by situation
Below are typical scenarios to illustrate how the total can vary based on choices and engine specifics.
- All four coils replaced with aftermarket parts: roughly $235–$610 total
- All four coils replaced with OEM parts: roughly $395–$730 total
- Only one coil replaced (common when the others are healthy): parts $40–$120, labor about $60–$120, total around $100–$240
Delivery of the final cost depends on your car’s exact model year, the chosen parts, and the local labor market, but these ranges cover typical scenarios for a recent Honda Accord.
When costs vary
Several factors can push costs higher or lower. These include regional price differences, whether the service is done at a dealership vs. an independent shop, whether diagnostic work is required, and whether additional maintenance (like spark plug replacement) is performed at the same time. If your car requires a dealer-level diagnostic or special tooling, expect to pay toward the higher end of the range.
Do-it-yourself considerations
For skilled DIYers with basic mechanics experience, replacing ignition coils on a Honda Accord may be feasible, especially on a straightforward four-cylinder engine. However, improper installation or missing torque specifications can lead to persistent misfires or damage. If you’re unsure, professional installation is advised.
Summary
In summary, replacing all four ignition coils on a Honda Accord typically costs about $235 to $730, depending on whether you choose aftermarket or OEM coils and on local labor rates. Purchasing only one coil, or pairing coil replacement with spark plug changes, can adjust the total accordingly. Always obtain multiple estimates and confirm whether diagnostic charges are included in the quote.
