Is your quote fair?
A quote between $180 and $409 is inside the band where half of all Toyota Corolla spark plug replacements landed. Below it is not automatically a bargain (four plugs on top of a four-cylinder); above it is not automatically gouging (iridium plugs on a V6 or V8, rear bank under the intake, coil boots replaced) — but both ends deserve a question.
What moves the price
- Cylinder count — eight plugs cost twice four — in parts and time.
- Access — rear-bank plugs on transverse V6 engines can mean intake removal.
- Plug type — iridium and platinum plugs cost more but last far longer.
