K&N oil filter

The K&N oil filters are avoided like the plague on motorcycle forums. Lots of leaks around where the nut is welded on, and incorrect placement of the sealing O-ring.

Personally I'd look at a different brand.

Dont do it! There are dozens of posts about problems with them. Over oiling can seriously foul up the carbuetor. Besides when all is said and done they actually are worse for filtering out dirt.

Why not just stick with......... Onan??????

Onan/Cummins/Fleetgard...all the same people. Use their filters. K&N is a marketing hype deal to make money selling an inferior product stated to make the world spin faster.

I've used K&N without any problems on my Harley and Duramax. Hype? Not buying it.

I agree and I'm a registered distributor of K&N products. Having said that, I use what I sell on everything including my pressure lubed lawnmower...

The only thing that may be of a concern with a K&N oiled type air filter is over oiling it may cause a MAF sensor issue on a gas motor because the oil vaporizes in the intake stream and fouls the MAF sensor. Other than that, never had an issue with any filter.

I think the negative comments about K&N are internet folklore perpetuated by stupidity.

Or actual events by people that I've corresponded with. K&N oil filters with the nut on the top are thoroughly vilified by people who have had them fail and dump oil directly in front of their rear wheel. Talk about something that will get your attention in a hurry. Either the filter starts to leak around the nut, or the O-ring is improperly placed to seal the filter, and that results in the oil getting dumped on the ground. Not hype, not internet folklore, real results from real people.

Obviously a registered distributor of K&N products will be totally unbiased. Riiiight.

I've used K&N air filters on my bikes for over 30 years, but I wouldn't put a K&N oil filter on anything I cared about.

Wow. I've used their air filters for decades. Thinking was nut would make removal easier.

Wrong. Just because I sell them don't mean I endorse their usage, why I put in the comment about the filters and the MAF sensor.

Now, that you've laid the groundwork for your claim... Care to provide a link and I mean not a heresay link but an actual substantiating link?

In all actuality, the spot welded on nut is font for tightening the filter, it's there for removal only. ANY AND ALL OIL FILTERS SHOULD ONLY BE HAND TIGHTENED OR, 1/2 TURN PAST THE POINT AT WHICH THE GASKET CONTACTS THE FILTER FLANGE No exceptions.

If you used the nut to tighten an oil filter (and deform the gasket or 'O' ring in the process, you are the nut doing it, not the spot welded nut on the end of the case....

So, having said that, pleas provide a substantiating link or cease commenting about things you have little knowledge about other than Internet 'knowledge'.

Okay here's one:

K&N Oil Filter Failure

Took a couple seconds on my VFR forum. Lots of reading there and several posters showing the results of a K&N oil filter failure. So there are issues.

Sorry that you feel you need to denigrate someone with an opposing viewpoint. Just stating the facts. So apology accepted.
