side gaped spark plugs on a 4.x
i know this is probly one of them off the wall question but has any one ever heared of side gaping spark plugs ? do the really make more power than regular spark plugs or is it another one of them things that every one says works but don't really work out in the long run i know they say you have to replace them after about 10,000 miles but don't you have to do that any way with ac delco plugs . I thought about doing this but i want to get some feed back on this before i did it i figure i got about another 5000 left on mine so if i did it and it didint work i got to replace them perty soon any way
