I used these plugs with Performance Distributors' Ignition Coil and Spark plug wires and my jeep ran poorly. One plug came cracked on the ceramic area, and I assume another was damaged as well. Thy don't sell these at local parts sores, so if one is bad, your stuck running another type or brand. I was getting misfire codes until I changed these out to something listed for my jeep model. I would only run these if you have a supercharger and programming set up for them. Did not work well for me.
