All the plugs looked great and only had minimal carbon. They did have a slight redish tint to them. The gap on the plugs removed were all close to .040. I gaped the new ones to .035. It does idle smoother as compared to before(still feels beastly) I did not notice any change in my 1/8 or 1/4 times. 0-60 is still the same also(I use a g-meter)
Snakz- What about going in through the fender well? I know that for exhaust manifolds and headers that's the best way to do it.
