First of all, if I'm going to spend $700 on my car, it won't be on these. That being said, has anyone looked into upgraded coil packs? I didn't see any hp boasts, but I'm sure it would help.

And they don't get much cheaper. They're $655 on ebay.
And at what point do you upgrade or change out the wiring going to the packs? It's only 16 or 18 gauge wire, there is a limit to what you can send through it. I wonder if putting higher draws on them with packs like these wouldn't really test the longevity of the wires.
