OEM Mitsubishi Spark Plugs

Mitsubishi Spark Plugs & Glow Plugs FAQ

How Can I Tell if the Spark Plugs in My Mitsubishi are Bad?

You'll know it from your engine misfiring, from the leads on the plugs seeming to have widened or corroded, and from the plugs not conducting electricity as well as they used to. At any rate, the ignition won't seem to work.

How Much Does Replacing My Spark Plugs Cost on Average?

$215 to $280 or so, according to RepairPal. Getting them replaced at a Mitsubishi service center versus going DIY can make up $130 to $165 worth of that. Cost can even vary by model; spark plug replacement for an Outlander, for instance, may run $170 to $260 or more total.

How Can I Extend the Life of My Spark Plugs?

The best way is to clean them regularly. That means wipe off any debris with a cloth (or blast it off with a can of compressed air), scrape crud off the firing ends with fine-grit sandpaper, and scrub the plugs' threads with a wire brush. Alternatively, you can spray the plugs with brake cleaner and then wipe them off.
