FYI, I have a 2006 Prowler and I wanted to change out the stock air filter with a K&N. Just wanting to replaced the filter not the air box I called my local dealer. The part number they are calling for does not fit. It does not have a proper groove cut in the filter. I went to K&N's web site and did a search by model I came up with a part number of AC-4004. I called the dealer and he confirmed with his K&N rep. So 2006 650 Prowler K&N air filter replacement is a AC-4004. Hope this helps guys and gals.

I have heard from some people that they didn't seal up well...maybe this will be the cure?

with alittle lube on the seal mine seams to be working good. Go to the K&N web site and look at the P/N I gave and see the groove that is machined for the air intake tube. It fits very good.

Prefilter

Here in Nevada we deal with lots of dust most of the year. The Arctic Cat stock air filter becomes clogged really quickly, and we know of a number of engines that were ruined because of dust. We took the original labyrinth tube off the rear of the air filter box, and replaced it with a reinforced rubber hose. The hose is routed on top of the skid plate to the front of the machine. We ran it to near the top of the radiator, and attached a UNI filter. Now we only clean the UNI filter; the stock filter, which is still in place, never needs cleaning.

Very interesting air intake system. Have you noticed any performace loss with the long tube??

 

[ElkoTrailRider]

None whatsoever, primarily because the tube is large diameter. Also, Arctic Cat was concerned that we would end up running too lean; I pulled the spark plug after 100 miles running with the new filtration system, and the plug was perfect color. A big plus to me is that it is much easier to remove the UNI filter for cleaning, as opposed to pulling the seats and engine cover!

Good point, sounds like you did your home work.

air filter kit for prowlers.

we have a custom built air filter kit which can either be used with a UNI foam filter, or a K&N filter with a UNI foam wrap. We have had no problems with this setup as far as sucking dirt or sand, and we see good HP numbers when combined with jetting, exhaust, and clutch kits. it removes the stock air box and will require a CVT filter as well.
