I wouldn't recommend these to my worst enemy

Comments On Nov 27, 2012:I put one on every machine i own. Quick and super easy to clean with less mess than the oily foam filter. Even better with the pre-filter cover

Additional Comments On Oct 31, 2014:I loved my K&N filters right up till I had to rebuild the engine on my 400ex after the K&N filter let in so much fine dust that the cylinder polished itself smooth. Couldn't detect even a hint of hone marks. We cleaned and oiled the filters after every ride (yes sounds excessive but they are that easy to maintain), used the pre-filter covers and always made sure the filter had a good seal on the intake tube so I know it wasn't neglect as some might think. We've since switched all of our filters back to the oily foam filters - not as easy to maintain but the extra effort is far better than another motor rebuild. I'll never own another K&N air filter!

Excellent Filter

Comments On Jun 10, 2014:I bought this to replace the stock filter. It is so much easier to maintain and much more durable for repeated cleaning.
