I've got the K+N Typhoon and compaired this to the factory system as well as BSRs and a few others. <p>OK, my biggest concern is that those others use the factory front air intake piece and the Typhoon doesn't ... <p>but is this even necessary? I mean K+N didn't feel so , however Volvo did. <p>doesn't the compressed intake charge heat up so much that this wouldn't be necessary. <p>what do you think?
