air filters

Post by oldishwinger » Thu Apr 02, 2015 5:15 pm

Hi folks,

I was just reading a a tread where a gentleman asked about oil filters, and the subject go onto air filters, particularly K&N Most comments where against the K&N air filters, because of letting in more air and therefore more contaminants etc.

Please, I dont want to start a bush fire here, but I have been using a K&N air filter in my 86 aspy now for about 6 years, and there has never been, one issue with it. I also know 1500 riders who use them again without issues.

The thing is, a K & N filter, cannot just be dropped in, like a OEM filter, the K&N one, needs to oiled, and the oil used, needs to be one that is made for the filter. it comes in spray can, as does the filter cleaner.

This is only my very humble opinion, but I cant see, how, a properly oiled K&N air filter, would let in more contaminants, than a OEM dry one.

Also with the use of the filter, there has been a definite small, overall improvement in the way the bike performs.

My question is: has anybody, who has used K&N air filters had any issues, with the bike, that could be related to the use of a K&N air filter?

Just to be clear folks, I have no affiliations with these filters, other than the fact I use one.

There have been study after study that have shown that K&N air filters, while they "flow" air much more freely, also allow far more contaminants through into the engine. I'm quite fine with spending a few dollars regularly on throw-away air filters, rather than spending huge money tearing my engine down to replace worn piston rings. ... study.html
