Frequently Asked Questions

How many plugs does the truck take?

The E07A is a three-cylinder, so it uses three plugs. Confirm the count in the listing and replace them as a set.

Do I need to gap them?

Check the gap against spec before fitting; a correct gap gives the cleanest idle and starting.

How do I read my spark plugs?

Pull them and look at the tip: light tan is healthy, black and sooty is running rich or weak spark, oily is oil burning, and white or blistered is running too hot. Check the gap against spec while they are out.
