I wouldn't use one....

I think for street use you can't beat them, but there have been a few people on this forum who have mentioned finding dirt that got by the K&N, that would have been stopped by a regular MX filter. I don't have personal experience with using one for MX, but after reading several posts about them passing fine dirt, I've decided to skip on the K&N.

Flintlock is right. K&N's are proven to pass dirt. They work great for cars, but not very well on dirt bikes.




And they will not give you 2-3 horsepower. :lol:

DO NOT USE A K&N ON A DIRT BIKE. They let in too much dirt and dust. If you ONLY track ride you might try it but I would clean and oil it before every race. I would never use a K&N for desert or any off-road use. You will not gain 2-3 hp either.

To summarize what has been said because I agree 100%:

An air filter will not give you 2-3 HP. Even on a car that makes 200HP, you would probably not see that amount.

K&N seem to work great on cars, but they do not offer the best protection from dirt and sand. I had one on my street bike, but it was never in the dirt.

The most important thing is to keep your air filter clean and oiled and make sure it is sealed/seated correctly.

Dirt Track bikes all run K&N air filters and have no problem with dirt getting through. Keep in mind they are not in an airbox and exposed to significantly more dirt than in an airbox.

They are also exposed to significantly less dust, generally speaking. Bad argument, I'm afraid.

The truth is that K&N filters actually filter better than almost all foam filters *IF* they are properly oiled. Unfortunately, this is so difficult to accomplish that very few K&N's ever get oiled thoroughly, and fail to stop dust because of it.

Ive got one on my 450 and it works fine if properly oiled like grayracer said. If Im riding solo its good, but if Im riding with a group in the desert I usually use a foam filter

Be careful if you use a K&N...they will pass their own oil if they are over oiled. I have had one on my truck...they are great because you do not have to reoil all the time..5-10k miles.....they make no since to me on a dirtbike:excuseme:
