Quick Answer — Ignition Coil Replacement Cost

Single ignition coil replacement: $65 – $450 (parts + labour)

Parts only: $15 – $120 per coil (aftermarket); $40 – $200+ (OEM)

Labour: $50 – $150 per visit (often stays the same whether you replace 1 or all)

Full set (4-cyl): $200 – $550 | Full set (V8): $500 – $1,200

Coils + spark plugs together: $250 – $1,100 depending on engine size

Luxury brands (BMW, Audi, Mercedes) and performance vehicles sit at the high end or above these ranges.

Your check engine light is on. The mechanic says it’s an ignition coil. And now you’re staring at a quote wondering if the number in front of you is reasonable — or if you’re about to get absolutely fleeced.

Let’s be honest: ignition coil replacement cost is one of those things most people have no frame of reference for until the day they need it. In this guide, we’ll explain replacement costs by vehicle type, ignition system, and engine configuration so you know exactly what to expect. If you’re unsure how many ignition coils your car actually has, read our detailed guide before estimating repair costs.

What Determines the Cost to Replace an Ignition Coil?

Before the numbers, it helps to understand why ignition coil replacement costs vary so much from one car to the next. There are four main factors at play:

1. The Type of Ignition System

Older cars with a distributor system have a single ignition coil — replace one unit and you’re done. Cars with a coil pack have 2–4 coils in a single housing. Modern cars with a coil-on-plug (COP) system have one coil per cylinder — potentially 4, 6, 8, or even 10 coils. More coils = potentially higher total cost if you’re replacing a full set.

2. OEM Parts vs Aftermarket Parts

A car brand OEM ignition coil is almost 2 to 3 times more costly. For all normal cars, a high-rated OE substitute brand (Denso, Bosch, Delphi,NGK) will work same. When you think of luxury or performance vehicles, price gap between OEMs and quality aftermarket are huge.

3. Vehicle Make and Model

A Toyota Corolla ignition coil costs a fraction of what a BMW 5 Series coil does — even though both are doing the same job. European luxury brands, performance vehicles, and some trucks carry a significant premium on parts.

4. Labour Time

On some cars, ignition coils sit right on top of the engine — accessible in 20 minutes. On others, they’re buried under intake manifolds, requiring a mechanic to disassemble half the engine bay just to get to them. Labour rates also vary by location and shop type — dealer workshops charge more than independent mechanics, typically by 30–50%. You can also review recommended vehicle maintenance schedules from the Car Care Council.

The most important thing to know about labour costs: In most cases, the labour charge to replace one coil and all coils is nearly the same — because the mechanic has to access the same area anyway. This is why replacing all coils at once on a high-mileage engine is almost always the smarter financial move.

Ignition Coil Replacement Cost By System Type

Cost to Replace 4 Ignition Coils (Full Set)

If you have a modern 4-cylinder that features coil-on-plug ignition, it’ll probably have 4 ignition coils in total – one for each cylinder. If a failed ignition coil turns out to be present in a high-mileage vehicle, one of the most frequently asked questions would be whether or not you should change them all.

Here’s the cost reality for replacing all 4 ignition coils:

• Budget aftermarket set (4 coils): $60–$120 in parts, $80–$150 in labour = $140–$270 total
• Quality aftermarket set (Bosch, Denso, NGK): $120–$200 in parts, $80–$150 in labour = $200–$350 total
• OEM parts (Toyota, Honda, Hyundai, etc.): $180–$320 in parts, $80–$150 in labour = $260–$470 total
• OEM parts (BMW, Audi, Mercedes): $300–$700+ in parts, $150–$250 in labour = $450–$950+ total

Money-saving tip: The labour charge to replace 4 coils is usually only marginally more than replacing 1. A mechanic who quotes you $80 for one coil will often charge $120–$150 for all four. Always ask for a quote for the full set — the per-coil cost drops significantly when you bundle them.

Ignition Coil and Spark Plug Replacement Cost Together

This is where smart car ownership starts making financial sense. When your mechanic is already in there replacing ignition coils, the additional labour to swap out spark plugs is minimal — usually an extra $30–$60 in labour for a complete set.

And here’s why you absolutely should do both at the same time: worn spark plugs are one of the leading causes of premature ignition coil failure. A degraded plug forces the coil to work harder to generate a strong enough spark. That extra strain shortens coil life. Replacing coils without replacing plugs is like fixing a water leak but leaving the damaged pipe in place.

Ignition Coil Replacement Cost by Popular Vehicle

Here’s where things get specific. The same job costs very different amounts depending on what you drive. These are realistic estimates for parts and labour combined at an independent mechanic — dealer rates will typically run 20–40% higher.

Can You Replace an Ignition Coil Yourself?

One coil replacement, on a many modern cars that have a coil on plug set up, is actually one of the easier DIY repairs that any shade-tree DIY mechanic can do. These are the plugs that the coils sit right over, easily accessible. On many of these models this involves…

1. Disconnect the battery negative terminal
2. Unplug the electrical connector from the coil
3. Remove the single bolt holding the coil in place
4. Pull the coil straight out
5. Insert the new coil, bolt it in, reconnect the plug
6. Reconnect the battery and clear the fault code

That’s legitimately a 20-minute job on a good day. A replacement coil for many mainstream cars costs $15–$60 from an auto parts store. The labour saving can be $80–$150 on a single coil.

• However – there are situations where DIY makes less sense:
• Turbocharged engines – heat cycles are more intense, coil access is often tighter
• V6/V8 with rear bank coils – rear cylinder coils on transverse-mounted engines can require significant disassembly
• Engines with intake manifold removal required – this is a full job, not a quick fix
• Luxury European vehicles – tolerances are tighter and mistakes are more expensive to fix

Important: Always use a quality OBD2 scanner to identify which specific cylinder is misfiring before buying parts. Don’t guess and replace the wrong ignition coil, as it wastes money and leaves the real problem unresolved. If the check engine light is already on, here’s what you should know before continuing to drive.

Signs Your Ignition Coil Needs Replacing (Don’t Ignore These)

The sooner you catch a failing ignition coil, the less collateral damage it does. A coil that’s been misfiring for weeks can foul spark plugs, damage the catalytic converter (a repair that costs far more than the coil), and in some cases cause fuel to wash down the cylinder walls.

Here’s what to watch for:

• Check engine light – A P0300–P0312 misfire code or P0350–P0362 coil-specific code are the clearest indicators
• Rough idle or engine misfire – That lumpy, uneven shake at idle is a cylinder not firing
• Loss of power under acceleration – A dead cylinder means you’re running the engine short
• Hard starting – Especially on cold mornings, a failing coil makes the engine reluctant to fire up
• Fuel smell from exhaust – Unburnt fuel passing through the misfiring cylinder exits through the exhaust
• Poor fuel economy – If your MPG has dropped without explanation, a misfiring coil is a likely suspect

How to Save Money on Ignition Coil Replacement

There’s no magic trick, but there are some genuinely effective ways to reduce what you pay:

1. Get multiple quotes – Labour rates between independent shops and dealerships can differ by 30–50% for identical work. Call three shops before committing.
2. Use quality aftermarket parts, not budget unknowns – Bosch, Denso, Delphi, NGK, and Motorcraft are trusted aftermarket brands. Avoid no-name coils from unknown sellers — they fail sooner and cost you more long-term.
3. Replace all coils at once on high-mileage engines – The labour is roughly the same whether you do one or all. Bundling saves you multiple callout charges over the next 12 months.
4. Do the spark plugs at the same time – Fresh plugs reduce stress on coils and often save $60–$100 in combined labour.
5. Ask about the warranty on parts and labour – Reputable shops typically offer 12 months / 12,000 miles on parts and labour. If they don’t, that tells you something.
6. Consider DIY on accessible coils – If your car has easily accessible COP coils and you’re comfortable with basic tools, the parts cost alone is a significant saving.

Key Takeaways

• Ignition coil replacement costs range from $65 to $450 for a single coil.
• Labour costs are often similar whether replacing one coil or several.
• Replacing spark plugs together with ignition coils can save on labour.
• OEM parts cost more, but quality aftermarket brands are often a reliable alternative.
• Fixing a faulty ignition coil early can help prevent catalytic converter damage and more expensive repairs.

The Bottom Line

The cost to replace an ignition coil ranges from around $65 for a simple single-coil swap on a budget vehicle, to $500 or more per coil on European luxury cars. For most people driving mainstream Japanese, Korean, or American vehicles, a single coil replacement lands between $90 and $280 all-in. A full set on a 4-cylinder runs $200–$470.

The smartest moves: get multiple quotes, use quality aftermarket parts rather than the cheapest option available, and strongly consider replacing all coils and spark plugs at the same time if your engine has significant mileage on it. The labour saving alone makes it worth it — and you’ll buy yourself another 100,000 km of reliable ignition performance.

Don’t ignore a misfire. A bad coil is a manageable repair. A destroyed catalytic converter from a prolonged misfire is a whole different conversation.

Tips to Reduce Ignition Coil Replacement Costs

• Compare quotes from multiple repair shops.
• Replace spark plugs with the ignition coils.
• Choose reputable aftermarket brands when appropriate.
• Diagnose the faulty cylinder before buying parts.
• Replace multiple ageing coils together on high-mileage vehicles.

Frequently Asked Questions (FAQs)

How much does it cost to replace an ignition coil?

Replacing a single ignition coil typically costs $65–$450 all-in (parts and labour). Budget aftermarket parts on accessible engines sit at the low end; OEM parts on luxury or complex engines sit at the high end. Labour alone is usually $50–$150 per visit regardless of how many coils you replace.

How much does an ignition coil cost to replace on common cars?

On mainstream Japanese and Korean vehicles (Toyota, Honda, Hyundai, Nissan), expect $90–$250 per single coil including labour. On European brands (BMW, Audi, Mercedes), budget $200–$500+ per coil. American trucks and SUVs typically fall in the $130–$350 range per coil.

What is the cost to replace 4 ignition coils?

A full set of 4 ignition coils on a 4-cylinder engine typically costs $160–$470 for mainstream vehicles, and $450–$950+ for European luxury brands. Labour is usually only marginally more than replacing a single coil, making a full set replacement excellent value.

How much does ignition coil and spark plug replacement cost?

Replacing coils and spark plugs together on a 4-cylinder typically costs $220–$600. On a V6, budget $280–$850. On a V8, $380–$1,100. Doing both in one visit saves $60–$150 in labour compared to two separate appointments.

Is it OK to drive with a bad ignition coil?

You can technically drive short distances, but it’s not recommended. A misfiring cylinder sends unburnt fuel into the exhaust system, which can destroy your catalytic converter — a repair that costs $800–$2,500+. A $100 coil that gets ignored can turn into a $1,500 repair. Get it fixed promptly.

How long does it take to replace an ignition coil?

On most modern cars with accessible coil-on-plug systems, replacing a single coil takes 20–45 minutes. Replacing a full set takes 45–90 minutes. On engines where coils are buried under intake manifolds, the job can take 2–4 hours — which is why labour costs vary so much between vehicles.

How long do ignition coils last?

Most ignition coils last 100,000–160,000 km under normal conditions. Premature failure is most commonly caused by worn spark plugs (which force coils to work harder), oil leaks contaminating the coil, or heat damage on turbocharged engines. Staying on top of spark plug replacements is the single best way to extend coil life.

Can I replace just one ignition coil, or do I need to replace all of them?

On average, most coils will last between 62,000-100,000 km (38,000-62,000 miles) before they need to be replaced during regular maintenance. Bad spark plugs (causing coils to have a tougher job), oil leaking onto the coil, or turbocharging creating excess heat can cause a coil to fail much sooner than the recommended period.
