Expecting my thank George refund this week and wondering how to spend it.
At least I'm wondering which FIPK kit to buy. Is the Air force one the best? Is it the only one that uses the orig. cold air intake? if so that alone seams like argument enough. Any opinions?
I had duals installed last week and I love the sound andd looks but don't believe I gained any noticable increase in power so now I'm going for the other end!

 

I own the airforce one and I wouldn't exactly say it "uses" the cold air intake. It uses an S&B filter which, unlike the others, is open on the end as well as the sides. I would guess that under full throttle, maybe 5 or 10% of the total air intake might be outside cold air. The rest of the air would most cetainly be inside engine compartment air. Johnny Lightning makes a ram air kit that is supposed to snug up against the end of the S&B...

Also, at WOT, be prepared... It is pretty loud under the hood. As I understand it, all the FIPKs are noisy.

Some here have mentioned wms velocity tubes. They use stock airbox to draw cold air. I invite opinions on this one... HP as good as a full FIPK?
