John, that is spectacular. I went back and looked at my old ones to see if I could find cracks... maybe I don't know where to look (Tone, is it a hairline crack?) Anyway, when I took out the old ones I didn't show them a lot of respect, so it's hard to say whether they were damaged or bad...
Anyway GLAD it fixed your problem. It's about time for me to get a supercharger...
