How much to replace a Toyota Corolla ignition coil?
The typical cost to replace a single ignition coil on a Toyota Corolla ranges from about $120 to $350, depending on whether you choose aftermarket or OEM parts and on labor rates. If you replace all four coils, the total typically falls in the broad range of roughly $390 to $1,220, again influenced by part choice and local labor costs.
What affects the price
Prices can vary based on several factors. Here is a breakdown of the key contributors to the final bill:
- Number of coils being replaced (one coil vs. all four).
- Type of part chosen (aftermarket vs. OEM Toyota parts).
- Labor rates at the repair shop and the estimated time to complete the job.
- Location and regional price differences, including taxes and shop markup.
- Whether additional components or related service (such as spark plugs or wiring inspection) are addressed in the same job.
Understanding these factors helps in comparing quotes and avoiding surprise charges when the work begins.
Typical price ranges
Below are commonly observed cost ranges for single-coil replacements and what you might expect when budgeting:
- Aftermarket ignition coil (single coil): $20–$60
- OEM Toyota ignition coil (single coil): $60–$180
- Labor to replace a single coil: $70–$170
- Estimated total for one coil (parts + labor): aftermarket $120–$260; OEM $130–$350
Notes: The exact price depends on your model year and engine variant, as well as your local labor rates. Some shops also quote a diagnostic fee if the failure cause isn’t confirmed yet.
Replacing all four ignition coils
If the technician advises replacing all four coils (common if a misfire is widespread or multiple cylinders are affected), the cost structure shifts to four-part pricing and broader labor time:
- Four aftermarket ignition coils (all four): parts $80–$240
- Four OEM Toyota ignition coils (all four): parts $240–$720
- Labor to replace all four coils: $150–$500
- Estimated total for all four coils: aftermarket $230–$740; OEM $390–$1,220
Again, these ranges reflect typical U.S. pricing in 2024–2025. High-cost regions and specialty shops may quote higher, while rates from independent mechanics or mobile services may be at the lower end.
What you should do next
To get an accurate figure for your situation, request written quotes from a few reputable shops. It’s wise to have the diagnostic results and the exact engine grade handy, since some codes (like misfires on specific cylinders) may indicate a single coil replacement, while others could suggest additional issues that affect the overall cost.
Summary
prices for a Toyota Corolla ignition coil replacement depend on coil count and part choice. Replacing a single coil typically costs about $120 to $350, while replacing all four coils generally falls in the $390 to $1,220 range, including parts and labor in most U.S. markets. Always obtain multiple quotes, confirm whether spark plugs or other maintenance are included, and verify if any diagnostic fees apply before proceeding.
