Interesting info on K&N filters

[r1rider98]

I think it even says that in the instructions. ( not to clean it so often)

[tonyrt44]

I use the K&N filter in desert, where fine sand, dust storms, and sand storms are normal.(if yoall seen dessert storm operation)
I have never seen any dust, sand, or anything else in the intake tube or engine. I service the filter every 2-3 months using Maxima synth. filter oil

this oil is great and will help tract all dust, not allowing it to pass the filter.

so are we worried that K&N sucks at getting all the dirt or are we worried that K&N doesn't flow as good as they have always said they have.


because if you oil your airfilters there is no way any dirt is getting through them. that's what stops the small peices of dirt anyway. and K&N don't do shit for power unless you have other stuff done. like exhaust or other mods.

so i'm confused as to what we are worried about now?

k&n flows good, doesn't clean as well. I agree, just need to keep that sucker oiled.

I did a little test this weeken, and we shall see how it turns out tonight. I cleaned my filter and outerware the night before our ride this weekend. While I was at it I put a light coating of WD-40 on the first 6" of the intake tube.


I'm taking bets on what the tube looks like.

Are you betting that it will be full of crap or do you think it will be clean?  I think it will be as clean as any other k&n type setup.

I'll bet it will be as clean as everyother K&N out there .............(being sarcastic)

Are we suppose to assume that a pleated paper is better than a gause cotton filter, goes against everything we've been told.

[who else but rk]

. and K&N don't do shit for power unless you have other stuff done. like exhaust or other mods.

im gonna have to disagree wit hthat. my rappy noticably changed power wise and power-curve wise with the k&n

Coming from the 7.3 liter diesel performance world I would 100% agree with that. They had a bad time with K&N filters "dusting" the turbos. When people started using paper filters such as what comes in the Sever Duty Filter kit that ford offers the turbos were in alot better shape. Those sever duty kits that ford offers is what the government ran in all there military vehicles in service in middle east. That right there would tell you about the filtering capibility of paper vs K&N.

So what are you trying to compare this to, paper, foam, other k&n type media or what?

I'm not really compairing it to anything. All I'm saying is that I like foam filters on motors I dont want to tear down every winter.

Maxx asked about the legitimacy of the test and I gave him my thoughts on the subject.

Its a fact that K&Ns let more than an acceptable amount of debris through.


I have done back to back tear downs on predators with the same intake, one with clamp on twin air and clamp on K&N filters. Both with outerwares. Ridden about the same amount of time, same areas, same oil, same everything.

The cylinder walls on the K&N were in worse shape than the twin air. The debris on the piston was more prevalent on the K&N.

Those are my findings, so take it for what its worth.

[maxx]

Could be worth alot.

It's like everything else in life. You have to strike a balance that works for you. I want max power, so I go with K&N. If you do the same oiled intake tube test but leave the same dirty filter, the tube will be cleaner. Paper is the best for dry conditions if it's not too restrictive and gets replaced very regular. Again, this assumes that you aren't throwing synthetic filter media into the mix. I don't know about the military stuff because I have only seen the Donaldson (synthetic)filters going overseas.
