Typical total cost ranges from about $100 to $300, depending on the plug type and local labor rates. Doing it yourself can push the cost lower, while reputable shops may charge more if additional parts or services are needed.
Understanding the price drivers
Several factors influence the final bill, including spark plug type (standard, platinum, or iridium), labor time, the shop’s hourly rate, and any extra services or fees. The Honda Fit’s 1.5-liter engine uses four plugs, with iridium-tipped plugs often chosen for longevity on newer models. Replacement intervals are usually around 100,000 miles for iridium plugs, but always check your owner's manual for the exact recommendation.
Plug type and pricing
Prices vary by plug type and brand. Expect four plugs to cost roughly $20–$60 in most markets, with iridium plugs typically at the higher end of that range.
Labor time and rates
Labor times commonly fall between 0.8 and 1.5 hours. At typical shop rates of $75–$120 per hour in the United States, labor can total about $60–$180.
Other fees and variables
Shop supplies, disposal fees, taxes, and any coincidence work (like coil or boot replacement) can add to the bill. If ignition coils or related wiring require service, costs rise.
Here is a straightforward breakdown of typical costs in the United States:
- Parts (four spark plugs): approximately $20–$60 (iridium or platinum, OEM or aftermarket).
- Labor: about $60–$180 depending on time and local rates.
- Shop fees/taxes/disposal: roughly $10–$25.
- Possible extras: ignition coils, gaskets, or misfire diagnostics if needed.
Most customers end up paying around $150–$250 in common scenarios, with higher prices in premium markets or when additional work is required.
DIY vs professional service
Replacing spark plugs yourself can significantly reduce costs if you have the right tools and follow manufacturer specs. Here’s what to consider if you go the DIY route:
- Tools and parts: four compatible spark plugs, ratchet, spark plug socket, extension, torque wrench, and basic hand tools; optionally anti-seize and dielectric grease as recommended.
- Steps: disconnect the battery, remove coil packs, carefully extract old plugs, check gaps, install new plugs to OEM torque specification, reassemble, and reconnect the battery.
- Precautions: keep track of ignition coil connectors, avoid cross-threading, and test the engine for proper operation after installation.
DIY can save money but requires time and care. If you’re unsure, a professional service helps prevent common mistakes and ensures proper torque and seating of the plugs.
Summary
For a Honda Fit, spark plug replacement typically costs about $100–$300, driven by the type of plugs and local labor rates. In many cases, customers see $150–$250, with higher costs in expensive regions or when extra work is needed. Doing it yourself can lower the price further if you have the tools and confidence.
What kills spark plugs quickly?
Pre-ignition can lead to heat building up in the combustion chamber causing the spark plugs to fail. In addition, if the cooling system isn't functioning correctly, it can cause the engine and spark plugs to overheat. This overheating can lead to the spark plug's electrode wearing out faster.
