How much does a coil pack cost to replace?

Expect to pay about $150–$450 to replace a single ignition coil or coil pack in the U.S. in 2025, including parts and labor; replacing all coils on a V6 or V8 can run $400–$1,300+ depending on vehicle, shop rates, and whether you use OEM or aftermarket parts. Costs vary with engine layout, access, and whether related items like spark plugs are serviced at the same time.

What a coil pack is—and why prices vary

A coil pack (or individual ignition coil on coil-on-plug systems) converts battery voltage into the high voltage needed for spark. Some engines use a single “pack” feeding multiple cylinders, while many modern engines have one coil per plug. Costs differ because parts prices and labor time swing with engine design, brand, and how hard the coils are to reach.

Typical 2025 price ranges

The following ranges cover common scenarios most drivers encounter. They reflect typical U.S. parts and labor at independent shops and dealerships this year.

• Single coil or coil pack replacement (most vehicles): $150–$450 total
• Full set on a 4‑cylinder (4 coils or one multi-output pack): $250–$900
• Full set on a V6: $400–$1,200
• Full set on a V8: $500–$1,300+ (high-end European models can exceed $1,500)
• DIY parts only: $40–$250 per coil; $75–$300 for a multi-output coil pack; $200–$900 for a full set

Your exact figure hinges on parts choice (OEM vs aftermarket), labor rates, and whether additional work—like spark plugs or intake removal—is needed.

Parts and labor breakdown

Here’s how the bill typically comes together at today’s shop rates.

• Parts:
  

  • Individual coil (coil‑on‑plug): $40–$150 aftermarket; $90–$250 OEM
  • Multi‑output coil pack (often older 4‑cyl/6‑cyl engines): $75–$300
  • Full sets: $120–$600 (I4), $180–$900 (V6), $240–$1,200+ (V8), depending on brand

• Labor:
  

  • Time: ~0.3–1.0 hour for an accessible single coil; 1.0–3.0 hours for full sets or hard-to-reach rear-bank coils
  • Rates: ~$90–$160/hr at many independent shops; ~$140–$220/hr at dealers in high-cost metros

Engines that require removing an intake manifold or cowl add labor time. Dealer parts and labor often run higher than independent shops.

What drives the price up or down

Several vehicle- and job-specific factors influence what you’ll pay.

• Engine layout and access (transverse V6 rear bank coils are often labor-intensive)
• OEM vs aftermarket parts (OEM typically cost more but match factory specifications)
• Dealer vs independent shop labor rates
• Bundled work (adding spark plugs, boots, or intake gaskets during the same visit)
• Regional labor-rate differences and taxes/fees

If a misfire has collateral causes—like worn plugs or a cracked coil connector—addressing those items adds cost but can prevent repeat visits.

Common add-ons you might see on the estimate

It’s normal for shops to recommend related maintenance or diagnostics alongside a coil replacement.

• Diagnostic scan/inspection: $50–$150 (often credited if you approve the repair)
• Spark plugs: $80–$300+ depending on plug type and engine access
• Coil boots/insulators or plug wires (where applicable): $20–$120 in parts
• Intake manifold/cowl gaskets if removed for access: $15–$80 in parts
• Shop supplies, taxes, and environmental fees: typically $10–$40+

Replacing aged plugs and boots with a new coil is good practice and can improve reliability and fuel economy.

When to replace a coil or coil pack

These symptoms often point to an ignition coil issue and justify testing or replacement.

• Check Engine Light with misfire codes (P0300–P0308) or coil circuit codes (P0351–P0358)
• Rough idle, stumbling, or power loss—especially under load
• Poor fuel economy and increased emissions
• Hard starting or intermittent no-start when hot or in damp weather

A quick scan and a simple coil swap test (moving the suspect coil to another cylinder) can help confirm the fault before buying parts.

DIY vs professional replacement

Many coils are straightforward to replace with basic tools, but access varies by vehicle.

• DIY-friendly if coils are on top of the engine and unobstructed; plan 20–60 minutes for a single coil
• Use dielectric grease on boots, follow torque specs, and clear codes afterward
• Avoid mixing up connectors, and inspect plugs/boots for carbon tracking
• Leave it to a pro if intake/cowl removal is required or if you lack a torque wrench and scan tool

DIY can save labor costs, but misdiagnosis or improper installation can cause repeat misfires or damage to the new coil.

Ways to save without cutting corners

Smart choices can reduce your final bill while maintaining reliability.

• Get quotes from at least two shops; independents are often less than dealers
• Ask for mid-tier aftermarket coils from reputable brands if OEM pricing is high
• Replace the failed coil only unless others show age-related issues; consider a full set on high-mileage engines with repeated failures
• Bundle spark plug replacement if they’re due—saves labor in the long run
• Look for coupons or membership discounts (roadside clubs, warehouse clubs)

Balancing parts quality with a trustworthy installer typically yields the best value and durability.

Timeframe and warranty

Most single-coil jobs are completed in under an hour; a full set can take 1–3 hours depending on access. Many shops offer 12-month/12,000-mile warranties on parts and labor; some aftermarket coils carry longer parts warranties. Keep your invoice for future claims.

Bottom line

In 2025, plan on $150–$450 to replace a single coil or coil pack, with full-set replacements on six- and eight-cylinder engines commonly ranging from $400 to over $1,300. Your price depends on parts brand, labor rates, and engine accessibility, and it may rise if spark plugs or gaskets are serviced at the same time.

Summary

Most drivers pay $150–$450 to replace a single ignition coil or coil pack, while full sets on V6/V8 engines can reach $400–$1,300+. Parts selection (OEM vs aftermarket), shop type, and how hard the coils are to reach drive the final cost. Consider addressing spark plugs and boots concurrently, and compare quotes from reputable shops to get the best value.

How much should it cost to replace a coil pack?

If you have a faulty coil, it’s going to cost you between $200 and $300 on average to replace it, not to mention the frustration and downtime you’ll experience. Learn more about what an ignition coil is, what it does, ignition coil replacement cost, and how you can tell when it’s bad.

Can I drive with a bad coil pack?

Driving a car with a faulty coil is not advisable, as it can cause the engine to misfire and potentially damage the catalytic converter.

How do I tell if a coil pack is bad?

Rough idle – The engine may shake or vibrate while idling. Difficulty starting – A failing coil may prevent the engine from starting altogether or cause it to crank a long time before starting. Poor fuel economy – A faulty ignition coil can lead to inefficient combustion, reducing fuel efficiency.

Why are coil packs so expensive?

Why are ignition coils so expensive? These are precision components. As a typical spark plug is fired eight times a second, ignition coil packs have to be well made. Being tempted by a low-quality part is a false economy.
