[QUOTE="SnakeBoostE85, post: 14365018, member: 160175"] You shouldn't really ever have to replace them, but depending on how often you rip on it or go to the track I would would pull them and re-gap every 5000 miles or so. When you pull them to re-gap if the electrodes or tips look worn, replace them. They come out of gap easily because of the amount of heat generated during WOT pulls. They expand and warp and eventually over time the gaps open up. This happened to me after I did my whipple install… I couldn't get the damn thing to stop blowing out, I almost replaced my coils until I thought to just check the plugs and verify the gap. So I pulled my plugs and noticed some were as far open as .038 all of them were well over .030. My original gap for just upper was .028 and that's what I use today even at 20 psi on the whipple and it works fine. Reminds me… I should probably pull them again. Its running fine right now, but might as well take an hour 1 weekend and pull them out. [/QUOTE]
