Star, ID: what's different here

How long does spark plug replacement take in Star?
A 4-cylinder engine usually takes about 30 minutes. A V6 or V8 commonly takes 1 to 2 hours. Hard-to-reach plugs in complex layouts can push labor to roughly 0.5 to 3.5 hours.

What to do next
- Count your engine's cylinders (4-cylinder vs. V6/V8) so your quote reflects the right labor time of 30 minutes to 2 hours.
- Ask the pro for proof of insurance and note whether the plugs are platinum or iridium, since those can cost up to $25 each.
- Request an itemized quote separating parts from labor hours, since complex layouts can push labor to 0.5 to 3.5 hours.
- Confirm the pro can work in your Star driveway, since newer suburban housing affects access for mobile repairs.
