Spark plug life span?

May 10, 2007 by archico01 | Posted in Maintenance & Repairs

What is the usual life span of a spark plug? What are the signs that I need to replace it?

Check the ignitor end and look for dark burnt spots. I change mine every 30000 miles or so, but that doesn't mean they need to be.

I love your rude answers | May 10, 2007
