My question is, is there a big differents in performance? I am ready to buy one just need some input on them. Airforce 1, K&N, or mac cold air. There's a site on ebay for $130.00 for this mac cold air kit.

 

well, i have a AF-1 and really like it. it was easy to install as well as added a decent amount of power. but i am pretty sure that the mac will do the same thing for you. i don't know why it wouldn't. but either way...good luck with your purchase.

 

I got the MAC. I bought it because they basically do the same thing, but one does it for less. Although the MAC is not stainless steel like the AF1. But they both suck air in from the same spot and both are mandrel bent so how different can they? Not much I say!
