Typically, replacing a single ignition coil pack runs about $100 to $400, depending on the vehicle, the part quality, and the labor rate. DIY replacement can reduce costs if you have the tools and expertise.
What you need to know about coil packs
Coil packs deliver the spark that ignites the air-fuel mixture in each cylinder. When a coil fails, you may notice rough idling, misfires, rough acceleration, or a check engine light. Some vehicles use individual coil-on-plug assemblies per cylinder, which can make replacement more expensive per unit due to access or part price.
Cost breakdown
Before you look at the numbers, note that costs vary by model, part brand, and local labor rates. The following breakdown gives you a sense of typical ranges.
- Parts cost: On many economy cars, a single aftermarket coil can be $20–$60, while OEM or higher-performance brands typically run $60–$150+ per coil. Coil-on-plug assemblies for some makes/models may exceed $150 per coil.
- Labor cost: Accessing and replacing a coil pack depends on engine layout. Expect roughly 0.5–2.0 hours at shop labor rates around $75–$150 per hour; complex or luxury vehicles can push this higher.
- Diagnosis/inspection: Shops often charge a diagnostic fee to confirm the misfire source, typically about $60–$120, sometimes waived if you proceed with the repair.
- Other costs: Taxes, shop fees, disposal charges, and any related maintenance (such as spark plugs) if they’re due at the same time.
Concluding the cost factors: the total you pay reflects both part price and labor. For older or harder-to-access engines, the total can be higher. When shopping, ask for a written estimate that clearly separates parts and labor.
Cost ranges by vehicle type
To give you a sense of typical totals across common vehicle categories, consider these rough ranges. Actual prices will vary by location and vehicle.
- Economy/compact cars: Parts roughly $40–$120; labor about $60–$180; total typically $100–$300.
- Midsize cars and light trucks: Parts $60–$180; labor $90–$230; total typically $150–$410.
- Luxury or European vehicles: Parts $120–$400; labor $180–$350; total often $350–$800 (or more for high-end brands).
DIY savings: If you can perform the replacement yourself, you can save the labor portion, which often represents a substantial share of the total cost.
What affects the price the most?
The biggest drivers are the coil type (single coil vs. coil-on-plug), whether you use aftermarket or OEM parts, engine accessibility, and regional labor rates. Complex layouts or high-end brands can push both parts and labor higher.
How to approach replacement
Start with diagnosing the issue to confirm a faulty coil (misfire codes such as P030x). If only one coil is failing, replacing that unit is usually the most economical option. Check whether spark plugs also need replacement, as worn plugs can contribute to misfires. Obtain multiple quotes from reputable shops and consider bundled maintenance if multiple coils or components are due.
Summary
Replacing a single coil pack typically costs $100–$400 in the United States, depending on the vehicle, coil type, and labor rates. Parts are cheaper with aftermarket units and more with OEM or coil-on-plug assemblies, especially on luxury or European models. Labor varies the most, driven by access and local rates. DIY replacement can significantly cut costs if you have the know-how and tools.
