Ignition coil replacement cost
Coil-on-plug failures often show as a cylinder-specific misfire; “replace all coils” should be justified, not automatic.
Typical U.S. independent-shop price range
$238–$320 national average for ignition coil replacement.
- Labor: $74–$109
- Parts: $164–$211
- Source: RepairPal — price data as of September 3, 2026. Excludes taxes, fees, diagnostic time, and your location. Related repairs may be needed.
What’s usually included
RepairPal’s national average covers ignition coil replacement parts and labor (typically one coil). Spark plugs, boots, and additional coils are commonly extra — ask how many coils and whether plugs are included.
Dealer vs independent
Dealers may prefer OEM coils; independents often use OE-equivalent. Compare whether the quote is for one coil or a set, and whether plug replacement is recommended with evidence of wear.
Common upsell red flags
- Full set of coils with no companion misfire codes or ohms/scope testing
- Catalytic converter scare from a short misfire without confirming catalyst damage
- Ignition tune-up package that buries line-item coil pricing
More patterns: spotting upselling.
Questions before you authorize
- Is this quote for one coil or all coils — and why?
- Which cylinder misfired, and did you swap-test or scope the coil?
- Are plugs included? What’s their condition?
- What’s the warranty if another coil fails soon after?

DIY vs shop
Often DIY-friendly on coil-on-plug engines with basic sockets; still confirm the misfiring cylinder. See DIY vs shop if access is tight.
