I wanted to get a K&N filter for my 05 wr450, but dont get how it mounts. I want one because all of our quads (sand) use them and I wanted one for my 450. Any clue to how it mounts?

Do yourself and your intake valves a favor and use a good quality foam filter on your WR. Do a search on K&N filters, they are proven to pass dirt and cause problems.

The problem I've seen with the one for a WR is it is a 2 piece, Like this
The top is a separate piece. Now you have two sealing surfaces to contend with.

I have heard of the same issues.
I do run the single piece ones on my quad and have in my cars.

What do you think the trucks in baja use along with some quads and bikes?

I could care less what everybody uses in baja. I use products based on what I have found thru research and real world experiences, not on what the quadtards in the desert think is best. :crazy:

Personally I wouldn't use a K&N in my lawnmower. They are not good in dusty conditions.

Damn Wild Ride.....That was a lot of good info. It will definitely keep me from putting a K&N in my bike....

A long time ago when I first started riding XRs, I tried K&N. I had problems with the sealing surface, saw streaks of crap in the airbox when I removed the filter. I tried several greases and even made my own gasket to replace the crummy stick-on gasket that came with the K&N, no luck, got tired of screwing with it and bought a UNI and have been using them ever since with no problems.

I had put a K&N in my DR 650 Dual Sport
First I had to re-jet LEANER :cheers:
I had constantly dirt / dust inside the intake manyfolds :crazy:
Oil consumption increased, cylinder and piston and rings ruined!! :lol:
K&N = no good! :ride:
After the engine rebuild I use a Twin Air, no more dirt past the filter, lots cheaper and easier to clean. :ride: Forget K&N!!! :cheers:
I asked my LandRover tuner about his opinion on K&Ns: "If you can look trough it, dirt will go through it.." rightly so! :cheers:

I got in contact with K&N, cylinder and piston and filter went to the US (from GER!). Of course I had ruined the filter using "other than K&N filter oil" (such as Twin Air or No Toil), they send me a new filter which of course I never installed.

SAE has got a standard out for the performance of automotive engine air filter (do not have the procedure number at hand). Recommendation is an efficiency of 99,9% under dusty (=OR) conditions. K&Ns never make that! If you want, I can figure out the respctive procedure number. Contact them and ask for their results!!!!
