Spark plug replacement from a mobile mechanic in Indianapolis, IN — the tech drives to you. Typically $150–$300 nationally. We're building coverage here now.
Nationally this job runs $150–$300. We haven't signed a Indianapolis mechanic who publishes a range for it — so rather than pad this page with a guess, here's the honest state of it.
Plug swap with gap-check; coil pack inspection.
Nationally this job sits at $150–$300. We don't yet have enough Indianapolis listings to publish a local band, and we'd rather say so than invent one. Four things move you inside that band: the vehicle first, then parts grade, then how far the tech drives to reach you, then whatever seizes or snaps on the way out. A quote that names all four is a quote you can trust; a single flat number usually isn't.
Every mechanic here publishes their own low-to-high for this job. Compare the bands, then call two — the first one who can roll is usually the right answer when the car is already down.
