Ignition Coil Replacement Cost (2026)
Replacing one ignition coil costs about $45–$170 at an independent shop in 2026: about $45–$170 on a 4-cylinder car and $65–$140 on a GM V8 truck. A full set of four costs about $95–$355. Manufacturers’ warranty times are 0.3–0.6 hour for all four coils on a 4-cylinder and 0.5 hour per side on GM’s V8 trucks. A flashing check engine light means stop driving: a severe misfire can damage the catalytic converter.

Diagnosis is often separate: parts stores and some chains read codes free, while a dealer diagnostic special we found was $99.95. Rear-bank coils on transverse V6 engines take longer; one Lexus hybrid V6 bulletin pays 2.8 hours for a coil plus engine-computer reprogramming. Before tax, shop-supply and disposal fees. Where we derive a total, labor is hours × $$100–$150 per hour[5],[6]. See the methodology.
DIY vs. shop vs. dealer
| Where | Cost | What you get |
|---|---|---|
| DIY | $15–$80One coil | On most 4-cylinders a coil-on-plug unit unplugs and unbolts in minutes. Swap the suspect coil with a neighbor: if the misfire follows the coil, the coil is bad.[1],[2],[8] |
| Chain / independent shop | $45–$170One coil | Coil plus labor at $100–$150/hr. Some chain stores scan codes free (one Meineke store posts a free code scan); a scan names the misfiring cylinder but isn’t a full diagnosis.[5],[6],[13] |
| Dealer | $140–$210Genuine Honda, derived | Genuine coil at MSRP and dealer labor rates ($125–$175/hr). A Toyota dealer posts a $99.95 check-engine diagnostic special.[10],[11],[12],[14] |
GM’s own misfire procedure tells technicians to swap the coil with an adjacent one and re-check before replacing anything, and not to replace injectors or the engine computer unless diagnosis points there.[8]
What drives the cost
- One coil or all: replacing only the failed coil is the cheapest fix; some manufacturer campaigns replace all of them (Hyundai, Kia and Mitsubishi bulletins replace every cylinder’s coil).[3],[4],[15]
- Brand: on a 2014 Camry, coils list from $21.79 to $162.79; the Denso OE-supplier coil is $66.79.[2]
- Engine layout: rear-bank coils on transverse V6s sit under the intake; Lexus pays 2.8 hours for one RX 450h coil job with reprogramming.[16]
- Spark plugs: the coils come off to reach the plugs, so if the plugs are due, doing both at once saves repeat labor (see spark plug replacement cost).
When you actually need it
A misfire sets codes P0300 (random) or P0301–P0308 (a specific cylinder). Hyundai’s bulletin ties cold-start P0300–P0304 misfires on the 2016 Sonata Hybrid to the coils; Mitsubishi traces P030X codes to poor coil terminal contact.[3],[15]
If the check engine light is flashing, stop driving hard and get it fixed: Ram’s owner’s manual says a flashing light means “severe catalytic converter damage and power loss will soon occur.”[17]
Coil failures can be covered by the federal emissions warranty: Lexus’ RX 450h coil bulletin cites its 8-year / 80,000-mile emissions coverage.[16]
If your check engine light is blinking, see the flashing check engine light.

Frequently asked questions
How much does it cost to replace an ignition coil?
About $45–$170 for one coil on a 4-cylinder car at an independent shop and $65–$140 on a GM V8 truck. All four on a 4-cylinder: about $95–$355. At a dealer with a genuine Honda coil: about $140–$210.
How much does it cost to fix an engine misfire?
It depends on the cause. A bad coil is usually $45–$170 at a shop; spark plugs, injectors, vacuum leaks or a head gasket cost differently. Diagnosis ranges from a free code scan to about $100 at a dealer.
Should I replace all ignition coils at once?
Not usually. Replace the coil that fails a swap test. Manufacturers replace all coils in some campaigns where a design fault affected every cylinder.
Can I drive with a bad ignition coil?
Avoid it, especially if the check engine light flashes. Unburned fuel from a misfiring cylinder can overheat and damage the catalytic converter.
How long does it take to replace an ignition coil?
Hyundai and Kia warranty times are 0.3–0.6 hour for all four coils on a 4-cylinder; GM pays 0.5 hour per side on its V8 trucks, including a coil swap test.
