theres a way around drilling a hole in your intake tube. i was watching one of those "car shows" on tnn this weekend, and they interviewed a guy from ZEX, and they make more of a "bolt on" kit, that they claim you can install in 2 hours. instead of drilling a hole in the intake tube, its kind of like a "cap" that fits over the end of your conical style air filter (kkm) with the nitrous line running to it. this is the first ive heard of anything like this, but it would be really cool if it turns out to not be a piece of crap.
