A single ignition coil for an Acura TSX typically costs between $40 and $120, depending on whether it’s OEM or aftermarket. Since the TSX uses four coil-on-plug coils, replacing all four could run roughly $160 to $480 before labor.
The Acura TSX, produced from 2004 to 2014, employs coil-on-plug ignition with four individual coils in the 4-cylinder setup. Prices vary by brand, condition, and where you buy them, so this article breaks down current market ranges and buying considerations to help you budget a repair or maintenance job accurately.
Pricing overview
The following ranges reflect common price points from dealerships, auto parts retailers, and online marketplaces for the TSX’s ignition coils.
- OEM (Honda/Acura genuine parts) coils: typically $60–$120 per coil.
- Aftermarket/new brands (Bosch, Denso, NGK, Accel, etc.): about $40–$90 per coil.
- Remanufactured or refurbished coils: roughly $25–$70 per coil.
- Used/ pulled-from-a-donor-vehicle: around $15–$50 per coil, depending on condition and seller.
Prices can vary by retailer, region, warranty terms, and whether the part is in stock, so it’s wise to compare several sources and check return policies before purchasing.
Brand examples and buying considerations
Some common scenarios include choosing OEM coils for maximum compatibility and warranty, or opting for reputable aftermarket brands that often offer substantial savings. When shopping, verify compatibility with your specific TSX model year and engine code (the 2.4L K24A engine uses four coil-on-plug units) and check for any VIN-specific fit notes from the seller.
Buying tips and considerations
Practical steps can help ensure you buy the right coils at a fair price and minimize the chance of misfit parts or future failures.
- Confirm engine details and number of coils: TSX uses four coil-on-plug coils on 4-cylinder models.
- Decide between OEM, aftermarket, or remanufactured: weigh price against warranty and perceived reliability.
- Check compatibility with your vehicle year and engine code: verify part numbers match your VIN.
- Compare sellers and look for warranties: a longer warranty can provide peace of mind, especially for aftermarket parts.
- Factor in labor costs if not replacing coils yourself: labor to replace multiple coils can vary by shop and total time required.
By following these buying tips, you can select coils that fit correctly and deliver reliable performance, while avoiding common pitfalls like improper fit or poor warranties.
Summary
For an Acura TSX, ignition coils generally cost about $40–$120 per coil, with four coils needed for a full replacement. OEM coils tend to be at the higher end of the range, while aftermarket and remanufactured options offer savings. Used coils can be cheaper but carry more risk. When budgeting, include potential labor costs if you’re not doing the work yourself, and always verify compatibility with your specific vehicle’s year and engine code. Shopping from multiple sources and reading warranty terms can help you land a fair deal.
