How often should you change sparkplugs?

Answer 1

It depends on what type of vehicle you own, mileage and year of vehicle. Usually its 10 years or 100k miles, whichever comes first. Easiest way to know is contact your dealer, notify them of your current mileage and ask if a tune up is due. REMEMBER; if applicable also replace your spark plug wires and distributor cap w/ rotor when doing a tune up!!! if you only change your plug you are simply changing the spark, not the current nor the distributing power.
