K&N or stock filter..?

7 posts in this topic

I was talking to the owner of a local bike shop the other day and he said not to use a K&N filter in sandy terrain. Since sand is just about the only terrain there is down here I was wondering how accurate his assumption was. I just bought a K&N and now I'm not sure if it was the right thing to do.

instead of stock get a no-toil or twin-air filter, much better than stock

K&N's are known for letting dirt pass thru them. Some say that when K&N's are oil properly that they work fine, but I'm not willing to risk my intake valves to find out.

IMO, a quality foam filter with a good sticky oil like Fab1, FFT, or PJ1 will serve you better than the K&N.

Any other opinions? I have only ridden the bike once since I got this $80 filter and I don't really want to buy another one.

If you havent used the filter yet take it back! Get what nfs179 said which was the no-toil or twin air filter which is foam also. I use the no-toil filter and the no-toil oil and love it! Iam thinking of getting the twin air filter since one of my sponsors is carrying it because they have the biodegradable oil like no-toil and makes cleaning a whole lot easier:thumbsup:

K&N air filters will both filter better and flow more air than most typical oiled foam elements IF they are cleaned and oiled correctly and completely. The problem is that this is much more difficult to accomplish with a pleated gauze element than with foam (it's every bit that important to do a good job with foam, too). The usual unfortunate result is that most K&N's in actual service are not properly prepared, and don't work well as a result.

IMO, the best thing to do in a sandy environment is to use a good high quality dual layer foam filter, and use a product like filter skins over it to keep sand from sitting on the filter.

Just always remember that it's the oil that filters, and not the foam.
