Ignition coil replacement cost depends mostly on how hard the coil is to reach, not only on the part price. As of November 4, 2026, a single coil job on a common engine is quoted as a range that covers parts and labor.
Engine layout, cylinder count and manufacturer bulletins drive most of the difference in ignition coil replacement cost. Confirm the failed coil before you approve a full set.
What is ignition coil replacement cost per coil?
Ignition coil replacement cost for one coil typically runs $142 to $234 for parts and labor, as of November 4, 2026, according to Jerry’s current guide.
The Jerry’s ignition coil guide lists parts at $40 to $100 or more per coil and labor at $80 to $107 or more per hour. Its full-set total runs $153 to $240 or more. Read these as ranges, not quotes, because prices move with the vehicle and region.
Mechanicbase, updated October 18, 2026, puts the average total at $200 to $300, with parts at $150 to $225. Its parts figure sits well above Jerry’s per-coil range, so the two sources do not agree. Both are consumer cost guides, not independent surveys, so treat every figure here as an estimate. Use the total ranges to judge the ignition coil replacement cost, and ask for a written quote that lists parts separately.

Why does access and engine size change the price?
For a hard-to-reach coil, ignition coil replacement cost is driven more by labor than by the part. Jerry’s sample quotes list a standard job at 40 to 50 minutes, while hard-to-reach coils add 2 to 4 hours.
- Standard coil job: 40 to 50 minutes of labor in Jerry’s sample quotes.
- Hard-to-reach coil: 2 to 4 hours of added labor, according to the same guide.
- More cylinders: $80 to $400 more in parts and $30 to $200 more in labor.
- Hard-access full set at a professional shop: $500 to $1,200 or more over 2 to 5 hours.
Design matters too. Jerry notes that newer cars usually have one coil on each spark plug, while older cars may feed several plugs through thick wires.
The labor line is the one to question in any ignition coil replacement cost quote. Ask how many hours the quote assumes and whether the coils sit in an easy-to-reach spot. If the hours look high for your engine, ask the shop to explain them before you approve the job.
Should you replace one coil or the whole set?
It depends on the manufacturer bulletin for your vehicle, not only on the ignition coil replacement cost. A 2016 MINI bulletin calls for replacing all coils at the first failure visit on N16 engines in service over 24 months or 10,000 miles.
The 2016 MINI service bulletin covers models R55 to R61 with the N16 engine. It names the replacement Eldor coils and says to continue diagnosis only if misfire or rough running remains after the coil work.
A 2013 GM bulletin takes a different route for 2009 Buick Enclave, Cadillac CTS and STS, Chevrolet Traverse, GMC Acadia and Saturn Outlook models with the 3.6L V6. It says to replace only the damaged coil when listed conditions are found. Otherwise, it says to change all six coils. Check whether your model is listed before you accept either path.
In Jerry’s ranges, the ignition coil replacement cost for a full set runs $153 to $240 or more, only a little above one coil. If a bulletin calls for all coils, a shop that replaces only one should be able to explain why.
Jerry advises replacing the full set when coils are buried, when mileage is higher, or when several coils are aged. Mechanicbase adds that on a coil pack, the entire pack must be replaced when one coil fails.
How do you confirm the coil is the fault?
A misfire code with a check engine light points toward a coil, but the bulletins call for checks first, before any ignition coil replacement cost is approved. The MINI bulletin says the misfire counter can identify the faulty coil without pulling spark plugs. A meter handles the wiring checks, as using a multimeter on car circuits explains. If the light is flashing, the misfire is active, so read what a flashing check engine light means before driving.
The GM bulletin lists rough running, a service engine soon light and shudder on acceleration as the usual complaints. Its codes are P0300 to P0306 and P0351 to P0356. Before you pay for a coil, ignition coil swap and resistance tests can confirm that it is the part that failed.
Mechanicbase lists a check engine light, hesitation or jerking under acceleration, stalling, rough idle, weaker fuel economy and hard starting as typical coil symptoms.
- Record every stored code and the misfire history for each cylinder on the repair order.
- Check the related coil’s power, ground and control wiring for opens or shorts.
- Inspect the top of the coil for heat or voltage damage. Traces under the epoxy are not damage.
Only a coil with visible damage falls under the bulletin’s replacement steps, so confirming it keeps ignition coil replacement cost down. If the coil looks sound and the wiring checks out, the bulletin states that it does not apply.
What else causes the same codes and wastes money?
Spark plugs, poor grounds and loose battery connections can produce the same misfire codes as a failed coil. The GM bulletin says removing the source of the problem, not only replacing the coil, prevents a repeat visit.
- Cracked, worn or wrong-gap spark plugs, and carbon fouling.
- Corroded, loose or under-torqued coil grounds and system grounds.
- Battery cables that are loose, corroded or not fully seated on the post.
- Connectors not fully seated at the under-hood electrical center.
The bulletin says to tighten the listed ground fasteners to 20 Nm (15 lb-ft) and warns against over-tightening. Ask the shop whether it checked grounds and battery connections before it replaced a coil.
Coils can also fail on their own. Mechanicbase names moisture, a fuel mixture that runs too rich or too lean, and extreme heat and vibration as causes. Jerry adds oil or water in plug wells and cracked boots, and says worn plugs shorten coil life. Mechanicbase says most coils should last 100,000 miles or more, so an early failure is a reason to check these causes first.
This list comes from one GM bulletin for the models named in it. Treat it as a checklist for that engine, not a rule for every car with a misfire.
Frequently Asked Questions
How long does an ignition coil replacement take?
A standard coil job takes about 40 to 50 minutes in Jerry’s sample quotes. Hard-to-reach coils can add 2 to 4 hours of labor, and professional hard-access full-set jobs run 2 to 5 hours in the same guide.
Does a misfire always mean the coil?
No. The GM bulletin notes that the cylinder with a damaged coil may not be the cylinder that misfires. Spark plugs, grounds and battery connections can cause the same codes, so check them before you approve a coil replacement.
Is a full set always more expensive than one coil?
The gap in ignition coil replacement cost is small in Jerry’s ranges. One coil runs $142 to $234, and a full set runs $153 to $240 or more, both with parts and labor. Whether a bulletin calls for all coils matters more than the price gap.
What labor rate should I expect?
Jerry lists labor at $80 to $107 or more per hour as of November 4, 2026. Rates vary by shop and region, which moves ignition coil replacement cost, so ask for an itemized quote that separates parts from labor hours.
Can a bulletin lower what I pay?
It can, if a bulletin covers your vehicle and engine, and that changes the ignition coil replacement cost you pay. Ask a dealer whether any service bulletin or warranty applies to your VIN before you pay out of pocket for a full set.
Before you approve any ignition coil replacement cost, ask for an itemized quote that shows parts, labor hours and whether the shop plans to replace one coil or all of them. Ask which bulletin, if any, supports that choice. If the hours or the coil count do not add up, get a second quote before you pay.
