Thanks guys.
I agree that a higher voltage spark could be beneficial to highly modified engine but in my case (Gotts mod w/ drop-in K&N, Magnaflow exhaust) and a Gryphon soon to be ordered, I'm sure the coil packs are not worth the hype. I've heard from a few shade tree motorheads that think it's the first step to an upgrade after intake & exhaust...but opinions are cheap. Thanks again for the input, no coil packs for me.
