for that kit, you are paying 135 bucks for a 20 dollar filter plus a few brackets..........

I made one myself, the filter cost 11 bucks at Kragens, I was too cheap to put a K&N on it, but if I find one on sale I might splurge..

i never did any tests, but i do not belive thier claim of up to 8hp...

contact them direct on thier website, the aircleaner can be bought without going thur ebay, see if you can return it if not satisfied.........
