In the United States, expect roughly $250–$450 total for a shop replacement of all six spark plugs on a Honda Pilot, with parts typically $60–$150 and labor around $180–$300. Doing it yourself can cut the bill to about the cost of the plugs alone, roughly $60–$150, plus any tools you may need.
Replacing spark plugs on a Honda Pilot is a common maintenance task that involves a V6 engine (3.5L in many model years). Prices vary by model year, plug type (iridium/platinum vs. copper), regional labor rates, and whether ignition coils or gaskets need replacement. Below is a detailed, up-to-date breakdown to help you estimate and plan.
What affects the price
The overall cost is driven by plug type, labor rates in your area, and how difficult the job is on your specific Pilot. More expensive plugs and higher local shop rates push the total up, while DIY execution or aftermarket parts can lower it.
Parts and labor breakdown
Costs are typically separated into parts (the spark plugs and any small consumables) and labor (the shop’s time to perform the replacement). The following list provides a general snapshot.
- Six spark plugs: aftermarket iridium/platinum plugs commonly cost about $8–$25 each; OEM Honda plugs can be $12–$25 each. Total parts for six plugs usually run roughly $60–$150.
- Small consumables and gaskets: anti-seize or dielectric grease, and a light gasket/seal item if needed; usually $5–$15 total.
- Potential extras: ignition coils are rarely replaced during a standard plug change, but if a misfire or worn coil is present, parts cost can rise significantly. Plan for additional $60–$150 per coil if replacement is necessary, plus labor.
In short, the parts portion is typically modest, while any coil-related issues or OEM parts can raise the bill. Availability of parts (OEM vs aftermarket) also affects price.
Labor time, rates, and total
The following ranges reflect common figures in the U.S. for a typical six-plug change on a Honda Pilot as of 2024–2026. Time and rates vary by shop and region.
- Estimated labor time: about 1.5–2.5 hours for a standard plug change on the 3.5L V6; in tight access areas, it can approach 3 hours.
- Labor rate ranges: independent shops commonly $90–$130 per hour; dealerships often $120–$180 per hour (some markets higher).
- Estimated total labor cost: roughly $140–$325 at an independent shop; $240–$600 at a dealership, depending on hours and local rates.
As with parts, regional price differences and whether the job is bundled with other maintenance can shift these numbers. Always request a written estimate that separates parts and labor before authorizing service.
DIY considerations
Is it worth doing yourself?
If you already own basic automotive tools and feel comfortable working on an engine, replacing six spark plugs can be a straightforward DIY project that saves labor costs. You’ll pay only for the plugs (roughly $60–$150) and any new tools you need. However, consider the time involved, the risk of cross-threading or improper torque, and the potential need for coil or gasket work if misfires or seals are present. If you’re unsure, a quick price check with a local shop can help you decide.
Summary
For most Honda Pilot owners in the U.S., a shop replacement of all six spark plugs typically runs about $250–$450 total, with parts around $60–$150 and labor around $180–$300. DIY can cut costs to the price of plugs plus tools. Prices vary by model year, plug type, coil condition, and regional labor rates, so it’s wise to get multiple estimates and confirm whether any additional parts or coil work might be needed.
