The cost of a replacement ignition coil for a car typically ranges from $50 to $350 for the part itself. However, the final price is highly variable and depends on your car's make, model, engine, and whether you use an OEM (Original Equipment Manufacturer) or aftermarket part. Labor for replacement adds another $50 to $200, bringing the total job cost to between $100 and $550. On average, most drivers can expect to pay around $250 to $400 for a professional to replace a single coil.
The primary factor influencing the price is the vehicle itself. A common 4-cylinder economy car will have much more affordable coils than a high-performance or luxury vehicle with a V8 or V12 engine. The type of coil system matters too. Modern cars often use individual coil-on-plug (COP) units for each cylinder, which are generally more expensive than older distributor-based systems.
| Vehicle Type | Typical Part Cost (OEM) | Typical Labor Cost | Total Estimated Cost |
|---|---|---|---|
| Standard 4-Cylinder Car | $75 - $150 | $70 - $120 | $145 - $270 |
| Common V6 SUV | $100 - $250 | $80 - $150 | $180 - $400 |
| Luxury/Performance V8 | $200 - $350+ | $100 - $200 | $300 - $550+ |
| Aftermarket Part (Economy) | $50 - $100 | $70 - $120 | $120 - $220 |
While a faulty coil can cause symptoms like a rough idle, loss of power, and the check engine light to illuminate, it's often recommended to replace spark plugs at the same time if they're due, as worn plugs can put extra stress on the new coil. For a confident DIYer with basic tools, replacing a single, easily accessible coil can be a straightforward job to save on labor costs. Otherwise, a trusted mechanic is your best bet for a proper diagnosis and installation.

It really depends on your car. For my old Civic, I bought a decent aftermarket coil online for about $65 and swapped it myself in 20 minutes. But if you have a newer European car or a truck, you could be looking at over $300 just for the part. Always get a proper diagnostic check first to make sure it's actually the coil and not just a spark plug causing the problem.

You're looking at a part cost between $50 on the low end for a basic aftermarket option to well over $300 for a brand-specific OEM part for a luxury vehicle. The labor isn't usually the biggest chunk of this repair unless the coil is buried deep in the engine bay. The best approach is to call your local auto parts store with your car's specific year, make, and model for an accurate part price, then get a quote from a mechanic you trust.

As a rule of thumb, budget between $250 and $400 for a professional to handle a single ignition coil replacement. This includes both the part and labor. The variance comes from your vehicle's brand and engine complexity. It's a critical component for engine performance, so while opting for a cheaper aftermarket part can save money upfront, using a quality part recommended for your engine is wiser for long-term reliability. Don't ignore the misfiring; it can damage the catalytic converter over time.

The price isn't one-size-fits-all. Key factors are the coil type—like coil-on-plug versus an older block coil—and the brand reputation of the part. A premium brand like Bosch or Denso will cost more than a generic store brand. If you're experiencing engine misfires, it's a repair worth doing promptly. While the cost might seem high for a small part, a functioning ignition coil is essential for efficient combustion, fuel economy, and preventing further damage to expensive emissions components.
