The ignition coil pack is a very important component in any vehicle’s ignition system. It delivers the high voltage required to ignite the air-fuel mixture in the engine’s cylinders. Over time, coil packs can fail due to heat damage, old age, or manufacturing defects.

Replacing a faulty coil pack is necessary to restore optimal engine performance and prevent issues like misfires, hesitation, and poor fuel economy. But what does a coil pack replacement cost?

In this guide, we’ll break down the average repair costs and factors that influence pricing. Read on to learn how to budget for this common vehicle maintenance task.

How Much Does Coil Pack Replacement Cost?

A coil pack replacement typically costs between $250 and $650 for parts and labor. The price can vary dramatically based on the:

• Make and model of vehicle – Luxury and high-performance cars often have pricier coil packs.
• Use of original manufacturer parts versus aftermarket components
• Extent of labor – More time consuming jobs on complex engine layouts cost more.
• Choice of mechanic or auto shop – Dealerships and specialty shops charge higher hourly rates.

While parts may only run $100 to $300, expect at least an hour or more of labor for installation. Diagnosing issues beforehand also adds to the total bill.

According to Rennlist.com, for example, the cost of replacing spark plugs and coil packs on a Porsche 997.1 was quoted at $350 for the plugs and $530 for the coil packs, with a total cost of $880.

AutoZone.com writes that the faulty ignition coil replacement cost can range from $200 to $300, with parts ranging from $35 to over $300 and labor costs usually less than $100.

JDPower.com notes that labor rates when you replace the ignition coil can range from $50 to $150 per hour, with an average cost of $213 to $295 for the replacement.

RepairPal.com reports that the average cost for an ignition coil replacement is estimated to be between $213 and $295, with labor costs estimated between $51 and $65 and parts priced between $161 and $230. This cost usually includes taxes.

A Reddit.com user was quoted $1,200 for the replacement of four ignition coils on a 2006 Honda Civic with 173,000 miles.

What Is a Coil Pack and Why Is It Important?

The coil pack contains an ignition coil for each engine cylinder rather than just one coil for all cylinders. This allows precise timing and distribution of voltage to each spark plug.

Without a functioning coil pack, the spark plugs won’t fire to ignite the fuel mix. This can lead to misfires, rough idling, poor acceleration, reduced power and fuel efficiency, or engine stalling. That’s why it’s crucial to replace bad coil packs promptly.

6 Common Signs Your Coil Pack Needs Replacement

Watch for these symptoms of a bad ignition coil pack, usually requiring you to consider car repair:

• Misfires or jerking – Especially under acceleration
• Rough idle – Engine feels shaky or unstable
• Loss of power – Reduced acceleration capability
• Poor fuel economy – Increased fuel consumption
• Flashing check engine light – Misfire error code
• Oil leaks – Caused by damage to ignition coil seals

DIY or Professional Replacement: Which Is Better?

Replacing coil packs yourself can save on labor costs, but has some risks:

Benefits of DIY replacement:

• Lower cost – No workshop labor fees
• Faster service – Avoid wait times at repair shops
• Learn about your vehicle – Opportunity to develop DIY skills

Potential downsides of DIY:

• Inexperience – Lack of expertise can lead to issues
• Special tools needed – Not all DIYers will have on hand
• Easy to damage components – If not careful
• No warranty on self-service
• Safety risks – Engine bays contain hazardous materials

The convenience and warranty coverage provided by professional replacement may be worth the higher cost for many drivers.

5 Tips to Save Money on Ignition Coil Pack Replacement

Here are some smart ways to minimize the expense of this repair:

• Buy aftermarket parts – Cheaper than OEM and often comparable quality
• Check online pricing – Research costs at local shops before booking
• Ask about package deals – Some shops offer discounts for multiple coil packs
• Inquire about remanufactured parts – Used coils that cost up to 50% less
• Negotiate on labor rates – Leverage coupons and memberships for savings

OEM vs Aftermarket Coil Packs: Which Are Better?

Most mechanics recommend OEM factory coils for optimal performance and reliability in late model cars:

Benefits of OEM coil packs:

• Engineered for your exact vehicle
• Highest quality materials and construction
• Ensure full ignition system integrity
• Preserve all electronic features
• Maintain warranty coverage

Aftermarket coil pack considerations:

• Significantly cheaper price over OEM
• Offer direct fit replacement for most applications
• Often made by reputable brands
• Can provide acceptable functionality
• Warranty may not match factory coils

Aftermarket coils are usually fine for older cars, but buy OEM for a modern vehicle you plan to keep long term.

The Step-By-Step Coil Pack Replacement Process

Replacing an ignition coil pack involves:

1. Disconnecting the negative battery terminal – To avoid shocks or electrical shorts
2. Removing ignition coil retaining bolts – Check manual for locations
3. Unplugging electrical connectors – Attach label so you can reconnect properly
4. Extracting coil from ignition module – Use care not to bend or break mounting tabs
5. Installing new coil pack – Ensure full contact with ignition module
6. Reconnecting connectors – Reference labels you attached before removal
7. Reinstalling retaining bolts – Tighten to torque specs in manual
8. Reconnecting the battery
9. Testing operation – Start engine to confirm normal performance

Always refer to the factory service manual for full procedures tailored to your specific vehicle.

How to Maintain Your Ignition System and Avoid Premature Failure

Regular maintenance is crucial to maximize the lifespan of your vehicle’s coil packs and avoid unnecessary replacement costs. Be diligent about:

• Replacing spark plugs – Helps ignition coils operate efficiently
• Using recommended spark plugs – Improper plugs increase failure risk
• Checking ignition wires – Replace any cracked or damaged wires
• Inspecting connections – Ensure tight, corrosion-free fittings
• Cleaning coils – Gently remove dirt and oil buildup on coils

The Bottom Line on Coil Pack Replacement Cost

While frequently overlooked, your vehicle’s ignition coils play a vital role in engine operation and drivability. Don’t ignore symptoms of coil pack problems. Budgeting $250-$650 for replacement by a professional mechanic is a fair rule of thumb, but research your specific vehicle’s repair costs. With periodic ignition system maintenance and prompt attention to any issues, your coil packs should deliver years of reliable performance.

FAQ: Coil Pack Replacement Questions

Can you drive with a faulty coil pack?

It’s not recommended to continue driving with a bad coil pack. While your vehicle may limp along, you risk additional damage from misfires. This can lead to lowered fuel economy, overheating, or even catalytic converter failure. Replace faulty coils promptly.

Is it worth replacing all coil packs at once?

If one coil goes bad, the others may be nearing the end of their lifespan too. Replacing the whole set together is cheaper than doing one at a time when they fail. Consider complete coil replacement if:

• Your coils are over 5 years old
• You prefer preventive maintenance
• Multiple coils test as weak or defective

Is it easy to replace a coil pack yourself?

Coil packs are generally one of the simpler ignition system DIY repairs. With basic tools and mechanical ability, most vehicle owners can replace their own coil packs after watching some tutorial videos. Just be sure to disconnect the battery properly and follow all precautions. Use a factory service manual as your guide.

Conclusion

Replacing worn or defective ignition coil packs is vital for proper engine performance and longevity. While parts are relatively affordable, labor and diagnostic fees can add up at professional shops.

With some basic information on costs and the replacement process, you can make an informed decision on addressing this common automotive repair.
