K&N powersports oil filters contain a modern synthetic filter media, designed for ultimate flow with less pressure drop, yet engineered for outstanding filtration. K&N powersports 'spin-on' oil filters feature a heavy-duty metal can. Most of these have a 17 mm nut affixed onto the end that allows for easy installation and removal. The 17 mm nut is crossed-drilled so racers can safety wire the filter to their bike. [MORE]

I installed the AC-1009 in my 2008 Arctic Cat Thundercat that has about 4000 miles on it The performance immediately increased in the higher R.P.M.'s The increase was noticeable in both engine response and power.

I highly recommend this item to help keep the off-road riding micro particals from possibly entering the engine. Installed on an arctic cat 400 4x4, it also helps extend cleaning periods to the filter!

Installing this filter dramatically improved the throttle response over the factory air filter. Installed on a 2006 arctic cat 400 4x4. I also purchased the dry filter cover to help keep out the small micro stuff for off-road use, which was highly recommended by a friend that is a atv mechanic!
