i have just the K & N filter and it did NOTHING for mine, thank god i
didnt pay full price as to me its useless, BUT thats just what i think.
i think i paid like 10 dollars for it from summit.
i bough nurf bars from summit and they sent me a 40 dollar off coupon
for next purhase, so i bought the filter and recharge kit, and it was a
waste of money i think, BUT again thats just what i think.
