The 2019 Honda Accord requires four spark plugs, and prices vary by brand, supplier and whether you choose OEM or aftermarket parts. In practice, you’ll spend roughly $20–$60 for a full aftermarket set or about $48–$100 for a dealer OEM set, with labor typically adding $100–$200 depending on your shop and location.
Parts options and price ranges
Prices depend on whether you choose aftermarket plugs or genuine Honda/OEM parts, and on the engine variant (1.5L or 2.0L Turbo) which both use four plugs but may have different part numbers.
- Aftermarket spark plugs (iridium or platinum) from brands like NGK, Denso, Bosch: typically about $5–$15 per plug; about $20–$60 for a full set of four.
- OEM/Dealer spark plugs (Honda-approved, iridium): about $12–$25 per plug; roughly $48–$100 for a full set of four.
- Premium or performance plugs can push prices higher, generally $15–$25 per plug; roughly $60–$100 for a full set.
Regardless of brand, four plugs are required for the 2019 Accord, so the total parts cost reflects four units rather than a single plug.
Labor costs and installation time
Labor costs depend on your local shop rate and the time required to replace all four plugs. Here is what you can expect:
- Estimated labor time for four spark plugs: typically about 0.8–1.5 hours, depending on engine access and technician efficiency.
- Shop rates vary by region, but common ranges are around $75–$150 per hour.
- Estimated total labor cost: roughly $60–$225 for common rates and times.
Some shops offer bundled pricing or promotions that include parts and labor for spark plug replacement, which can improve value.
Tips to save and ensure proper installation
To get the best value and ensure reliability, consider these guidelines before buying and scheduling replacement:
- Check the owner’s manual for the exact replacement interval and part numbers for your engine (1.5L or 2.0L Turbo).
- Match the plug type and heat range to Honda’s specifications; using the wrong heat range can cause misfires or poor idle.
- Use the correct torque specification when installing plugs to avoid thread damage; consider using anti-seize only if specified.
Following these tips helps ensure a reliable install and long plug life, while potentially saving money on labor and warranty considerations.
Summary
For a 2019 Honda Accord, four spark plugs are required. Expect roughly $20–$60 in parts for aftermarket plugs or $48–$100 for OEM plugs, with installation labor typically $60–$225 depending on rates and time.
