Honda Accord — Spark Plug Replacement Cost
What owners actually paid
The shaded middle is where half of all these repairs landed: $172 – $413. A quote inside that band is normal. Cheaper or pricier isn't automatically wrong — but it's worth asking why.
Real repair reports
These reports are a recent sample of real, paid Honda Accord spark plug replacement visits — quoted the way the owner and the technician actually said it.
Car owners said
“Diagnose check engine lite”
“Running rough by our records never has had fuel filter, air filter, plugs”
“spark plugs, trans service”
“* Replace the spark plugs”
“Diagnose check engine light on”
What this repair is
Spark plugs ignite the fuel in each cylinder. Worn plugs cause rough running, misfires, poor fuel economy, and eventually a flashing check-engine light. Modern plugs last 60k–100k miles; the price is mostly labor, which varies hugely by how buried the plugs are on your engine.
Is your quote fair?
If your quote lands between $172 and $413, it's inside the range where half of all real Honda Accord repairs of this kind land — and the typical job takes about 1.5 hours of labor. Quotes well below aren't automatically good news (economy parts, or related work skipped) and quotes above aren't automatically gouging (trim variants, premium parts, seized hardware) — but both ends deserve questions.
