Replace One Coil or the Full Set?

The answer depends on your mileage.

Under 60,000 miles: Replace one

Other coils are far from end-of-life. Save money and replace just the confirmed bad one. Confirm with the coil swap test first.

80,000+ miles: Replace all

Same age, same heat cycles. At $125/hr, replacing one now + one in 6 months costs more than replacing all four at once. Break-even typically crosses at 60-80k mi.

Frequently Asked Questions

How much does it cost to replace an ignition coil?
An ignition coil replacement costs $80 to $350 per coil at a US shop in 2026, parts and labour combined. Replacing the full set on a 4-cylinder runs $220-$520, V6 $330-$780, V8 $440-$1,040. Labour is 0.3-1.1 hours per cylinder at $90-$162 per hour depending on shop type and engine access. Source: AllData flat-rate hours, 2026 RepairPal Mechanic Rate Index.
Should I replace just one ignition coil or the full set?
Under 60,000 miles: replace just the failed coil. At 80,000 miles or more: replace them all. The other coils are the same age and have the same heat-cycle fatigue. At $125 average labour rate, replacing one coil now at 90k miles ($100) plus another in 6 months ($100) costs more than replacing all four now ($187 on a 4-cylinder).
Can I drive with a bad ignition coil?
Short-term, yes. Long-term, no. A misfiring cylinder sends raw unburned fuel into the catalytic converter, which can melt the substrate and cause a $1,000-$2,500 cat repair. A steady check-engine light with a misfire code allows 1-2 weeks of careful driving. A flashing check-engine light means active catalytic damage is happening right now. Tow it.
How do I know if it is the coil or the spark plug causing the misfire?
Use the coil swap test. Move the suspect coil to a different cylinder and clear the codes. If the misfire code follows the coil to the new cylinder (e.g., P0301 becomes P0302), the coil is bad. If the code stays on the original cylinder, the spark plug, injector, or compression is the real problem. This takes 10 minutes and saves you buying an unnecessary part.
Can a bad ignition coil damage the catalytic converter?
Yes. Raw fuel exiting an unfired cylinder reaches the catalytic converter, where it ignites and melts the substrate. Catalytic converter replacement costs $1,000-$2,500. The flashing check-engine light is the warning signal that this damage is happening in real time. Any active misfire code (P0300-P0312) should be repaired within 1-2 weeks to prevent cat damage.
Should I replace spark plugs when replacing ignition coils?
Yes, if your plugs are past 60,000 miles or are copper plugs. The coils are already removed, so adding plugs takes 5 extra minutes per cylinder and costs $24-$60 for a full set. Worn plugs force coils to generate higher voltage, which shortens coil life.
How long do ignition coils last?
Most ignition coils last 60,000-100,000 miles. OEM and premium aftermarket (Denso, NGK, Bosch) hit 80,000-130,000 miles. Cheap no-name coils fail at 25,000-40,000 miles. Coils also fail by age alone (10-15 years) regardless of mileage. There is no fixed service interval.
What is the difference between a coil-on-plug and a coil pack?
Coil-on-plug (COP) means one coil per cylinder mounted directly on the spark plug. Most cars built since 2000 use this. A coil pack is one unit that fires 2-4 cylinders via plug wires (waste-spark configuration), common on 1990s-early 2000s vehicles. When a coil pack fails, multiple cylinders misfire at once. COP failure affects one cylinder and produces a specific P030X code.
