the main reason the the K & N intake system is likley the best out (or soon to be out) is that it is automotive grade plastic
Plastic is superior in this application because:
-plastic is a terrible conducter of heat, ever touched an aftermarket aluminum intake tube? it gets hot. Cooler denser air makes more consistant power, modern composite intake manafolds are an example of this.
(have an '05 GT? go for a drive, get it hot, pop the hood and grab an intake runner)
-plastic is formable, the right hand elbow bend can be blown up larger and the shape tuned for smoother air flow (can't really do that with aluminum)
no, I don't work for K&N just thoughts / opinions
update 6-14-05, the K&N in it current state is not my top choice for max performance. the JLT and a tuner (when I can afford it) will be on my short list, I believe all still holds true for the wonders of plastic
