Expect to pay roughly $150–$350 for a 4-cylinder 2014 Accord, and about $250–$550 for a V6, including parts and labor; exact figures vary by shop, location, and plug type.
The 2014 Honda Accord offers two engine options: a 2.4L four-cylinder and a 3.5L V6. Replacement costs depend on the number of plugs, the type of plugs (copper, platinum, or iridium), labor rates in your area, and how accessible the plugs are. In many cases, labor is the larger portion of the bill because the plugs are buried under components or tied to coil-on-plug assemblies. This guide outlines typical costs and what can influence them, to help you budget and shop around.
What affects the price
Several factors determine the final charge when replacing spark plugs on a 2014 Accord. Here is a breakdown of the main considerations:
- Engine type and number of plugs (4 for the 2.4L, 6 for the 3.5L)
- Plug type and brand (copper, platinum, or iridium) and whether OEM or aftermarket parts are used
- Labor rate in your area (dealer vs independent shop vs quick-lube chains)
- Accessibility and required disassembly (coil packs, intake components, or other obstructions)
- Any included inspections or related services (coil checks, ignition system inspection, or cleaning)
- Geographic cost variations and local demand for skilled automotive service
Understanding these factors can help you compare quotes and decide whether to use OEM plugs or an aftermarket option, and whether a dealership or independent mechanic is likely to offer the best value.
Estimated price ranges by engine
These ranges provide a budgeting guide for common configurations. Exact quotes will depend on your location and the shop you choose.
Four-cylinder 2.4L (four spark plugs)
Parts and labor breakdown for the four-cylinder engine.
- Parts: typically $20–$120 depending on plug type (copper vs. platinum/iridium)
- Labor: approximately 1–2 hours at $80–$150/hour, depending on shop and region
- Estimated total: about $100–$420
Note: Many shops quote in the $150–$350 range for a 4-cylinder spark plug replacement, depending on local rates and whether any extra checks are included.
V6 3.5L (six spark plugs)
Parts and labor breakdown for the V6 engine.
- Parts: typically $30–$210 depending on plug type
- Labor: approximately 1.5–3 hours at $80–$150/hour, depending on shop and region
- Estimated total: about $150–$660
Note: The V6 replacement generally costs more due to more plugs and longer labor time, with many quotes falling in the $250–$550 range.
What to expect at the shop
When you shop for spark plug replacement, you’ll commonly encounter the following process and options:
- Diagnosis and confirmation of plug type and replacement interval according to Honda’s schedule
- Removal of ignition coils and any obstructing components to access the plugs
- Installation of new plugs with proper torque specification and anti-seize/thermal compounds if recommended
- Possible inspection of ignition coils and related ignition components
To avoid surprises, request a written estimate that separates parts and labor, and ask whether the price includes any post-service checks or a short test drive to confirm proper operation.
Summary
For a 2014 Honda Accord, spark plug replacement costs are primarily driven by engine type and local labor rates. A 4-cylinder model typically falls in the $150–$350 range, while a V6 model commonly runs $250–$550. Always obtain a detailed quote before service, consider plug type and OEM vs aftermarket parts, and remember that region and shop choice can swing the total price.
