Just LOVE those air filters ! I got 2 of those baby ones on my Kawasaki 250 KXF 2012 and one on my KTM 450 SMR 2006. Easy to install, remove, clean up and reinstall. Takes me 10 minutes. I like the sound made by installing them (compared to the original one). Love the quality of the air filter but mostly love the improvement of power that they add to my bikes.For me racing with an original air filter is simply not possible! When you compare the price of 1 K&N to multiple originals that you need to change, after a while, at the end it's money saved. I never had any probleme with any of them (even in France I was using K&N on my street bikes).

I ordered 2 of these filters as they were the specific part number listed for my 2003 Polaris rmk 800 vertical edge chassis. When trying to install, I found that there is no clearance between the inside carburetor and the steering column. So I was stuck with a decision to go back to stock airbox or figure out something else entirely. Since I needed the better airflow for my sled, I ended up gutting my airbox and custom mounting one of the filters to stick out of the top of the air box and out of the hood. This worked great except I now have an extra filter. Fortunately I have another of the same sled so I was able to do the same modifications. I just want to inform K&N filters that these filters DO NOT fit that model snowmobile and that it should look into changing the filter design with a groove or something on the side of the steering column so it will fit properly. I would have preferred much more to have a single filter for EACH carb. Other than that, I am happy with the filters, but am frustrated that I spent so much time searching the site for a filter that would fit after I discovered the inside filter wouldnt fit and the time I had to spend to figure out and to the modifications for the custom mount when they should have just clamped on the end of the carb off the get go. I will recommend k&n to anyone, but am disappointed that this issue wasn't discovered sooner. Thanks for your time.

RZR XP 900 Air filters and oil filters from K&N were perfect fit and finish when they were installed. I know the quality of the K&N products will protect the engine of the Polaris for many races in the future. We can rest assured that we will be able to concentrate on the rest of the car. To this date we have had no failures from any of our K&N Products.
