Take a 5/8 spark plug socket, I'm pretty sure its 5/8 if not it'll be 13/16. You will most likely need an extension atleast 2 inchs long. Your spark plugs are located in between runners on your exhaust manifolds in the head. Break them loose, unscrew them, find out what you need to gap the plugs to, using a feeler gauge to check the gap, smash the prong on the spark plug until desired gap is reached, install new spark plugs, only hand tighten, DO NOT torque spark plugs into the heads you'll regret it later on.
