Replacing a single ignition coil on a Honda Pilot typically costs about $150 to $350, while replacing all six coils at once generally runs around $600 to $1,200, depending on parts and labor rates. This article breaks down the price drivers, what to expect from a shop, and money-saving tips.
What you’re paying for and how costs break down
The Honda Pilot’s 3.5L V6 uses six ignition coils—one coil per cylinder—clustered in a coil-on-plug arrangement. When a coil fails, a misfire can occur, the check engine light may come on, and engine performance can suffer. Prices vary by model year, region, and whether you choose aftermarket or OEM parts, and whether you replace just one coil or all six. The following breakdown covers the main price drivers you’ll encounter.
Cost components you’ll typically see when replacing a single coil or all six:
- Parts: ignition coil price per cylinder. Aftermarket coils generally run roughly $40 to $90 each, while Honda OEM coils tend to be in the $70 to $150 range per coil. For six coils, multiply accordingly.
- Labor: labor time depends on access and whether you replace one coil or all six. Expect about 0.5 to 1 hour per coil under normal conditions, with shop rates commonly between $80 and $150 per hour. That means roughly $40 to $150 in labor for a single coil, and $300 to $900 for all six.
- Spark plugs (optional but common at higher mileages): about $5 to $15 per plug, or $30 to $90 for six plugs. Some shops include plugs if they’re due for replacement.
- Diagnostics: a diagnostic fee may apply if you’re not replacing parts that were diagnosed as faulty. Typical ranges are $80 to $150.
- Miscellaneous/taxes: shop supplies, disposal fees, and taxes can add a small amount to the total.
Prices vary by location, vehicle year, and the shop’s pricing structure. It’s always wise to get a written quote before authorizing work.
In summary, the cost to replace a coil on a Honda Pilot hinges on how many coils you replace, part choice (aftermarket vs OEM), labor rates, and whether you add spark plugs or diagnostics. A single-coil replacement tends to be in the low-to-mid hundreds, while replacing all six can push toward the high hundreds or into the low thousands depending on parts and labor.
Single coil vs. multiple coils: when to replace what
When replacing a single coil makes sense
If diagnostic tools point to a specific cylinder showing misfire or performance issues, and the other coils are relatively fresh, replacing only the faulty coil is standard practice. This minimizes upfront cost and downtime while addressing the root cause.
When replacing all six coils is worth considering
If the vehicle has high mileage and multiple coils show signs of wear, or you’re aiming for long-term reliability, some owners opt to replace all six coils at once. This can reduce future labor charges and the risk of additional coil failures soon after a single replacement.
What to ask your mechanic
Before authorizing work, request a written estimate that itemizes parts, labor, diagnostics, and any additional services (like spark plugs). If you’re on a budget, ask whether aftermarket coils are appropriate for your vehicle and whether plugs should be replaced now or deferred. Check warranty terms on both parts and labor for peace of mind.
Summary
Replacing a coil on a Honda Pilot costs roughly $150–$350 for a single coil and about $600–$1,200 for all six, depending on parts and local labor rates. Costs will be higher for OEM parts and lower for reputable aftermarket options. Always get a written quote, consider whether plugs should be replaced at the same time, and weigh replacing one coil versus all six based on mileage and reliability needs.
For readers seeking the latest, local pricing, contact a few independent shops or a Honda dealership in your area, and compare parts choices (OEM vs. aftermarket) along with current labor rates to get an precise figure tailored to your vehicle’s year and condition.
What are the signs of a failing coil pack?
Signs of a Bad Ignition Coil
- Illuminated Check Engine Light. With most modern vehicles, a faulty ignition coil is enough to turn on the Check Engine Light.
- Misfiring Engine. If an ignition coil is not working properly, your engine will likely misfire.
- Hard Starts.
- Worsening Gas Mileage.
- Diminished Power.
- Sudden Backfires.
Can I drive with one bad ignition coil?
Technically, you might still be able to drive with a failing coil, especially if your vehicle has multiple coils and only one is malfunctioning. But it's not a good idea.
How much do mechanics charge to change coil packs?
The average cost to replace an ignition coil is between $230 and $330, according to RepairPal. This cost includes both labor and parts. Labor is estimated at $75 to $100, while the cost of parts typically ranges from about $155 to $230.
