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 $167 and $415, it's inside the range where half of all real Honda Civic repairs of this kind land — and the typical job takes about 1.6 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.
