Is A K&N Air Filter Worth Buying?

[ford832]

Did you use a Uni or Twin Air vintagebluesmoke?If so,did you oil them?Did they seat against the airbox?No foam filter with out seating or damage issues would ever pass a piece of wood-even if it was dry.I've seen exactly the same thing as metalmike.I had one on my quad and I've been around them all my life and always have seen the fine dirt in the intake tract when they're used-and it stops when they're filed in the round bin.They've been tested many times times before and they don't filter down to as fine a micron as a quality oiled foam filter-unless you read the K&N ads.I bought in when I was younger too but saw enough over the years to change my tune.K&N's do go longer without needing to be serviced than an oiled foam filter and they are better than the hokey paper one that comes in your truck but I'd never again put one in one of my toys.

BTW,Sachs,the advantage of running a bird nest filter in the YZ is that I can make soup out of it after my ride.Lets see you try that with Adolph's sock.

I'm actually considering a K&N filter for an evolution class project I'm working on.I have to custom fabricate the airbox - looks like I need to do some more research.

Ford,are you referring to a sock that likes to goose step?

For a better understanding of just how a K&N filter works, fast forward to 6 minutes.

Despite the 80's glasses and goofy hair  , few people will dispute Vizard's wisdom and knowledge.

My Uni and Twin Air filters were well oiled with Silcoline filter oil, seated with bearing grease (nothing passed through the seating). What passed was hardly larger than sand but like slivers or toothpicks (only smaller).

I could ask the same thing? Was the K&N properly oiled? Was it properly seated?

[ford832]

Yes indeed,seated,greased,double checked,re-oiled and greased at the mounting point the second and third time with the airbox recleaned on the quad every time just to confirm my initial results.The design of my quad airbox also eliminates the possibility of debris falling into the intake upon filter removal-making it look like dirt is passing when it's not.I guess we'll have to agree to disagree.
