    Re: K&N Air filter

    Does the defendant have any proof that they let more dirt into the engine?

    Absolutely:



    Testand Corp of Rhode Island performed a ISO 5011 Test of several filters for a Duramax diesel.

    The ISO 5011 Standard (formerly SAE J726) defines a precise filter test using precision measurements under controlled conditions. Temperature & humidity of the test dust and air used in the test are strictly monitored and controlled.

    Here are the efficiency results:



    The K&N also plugged up 3 times faster than the AC Delco.

    I had one in my V6 for about a year, then went back to a regular one because I realized it was pointless and a waste of time (the cleaning, re-oiling).

    Re: K&N Air filter

    It's curious that GM never took advantage of this performance and fuel mileage change to get better advertising figures and better CAFE specs.

    (The K&N sticker is where the real horsepower is - especially when stuck on the RR passenger window so the ricer driver sees it at stoplights.)

    The "arguments" for using oil wetted filters are laughable ..........

    The quote is from "Stroker McGurk" which was a monthly cartoon with McGurkisms in Hot Rod magazine. The one I liked best is, "If a little is good, more is better, and too much is barely enough". Sub409 is partial to, "If it don't go, chrome it".
    K&N built their reputation with wetted foam filters for dirt bikes. They worked better than the alternates for the time. If your bike was outside when it rained, you were going nowhere until you took the filter off and wrang it out. I quickly reverted to paper filters on my 810cc Dunstall Norton.

    Re: K&N Air filter

    The K&N dirt bike filters had a foam rubber element that was wetted with motor oil. AC made a similar filter for aircraft to replace Donaldson filters that were constructed like the current K&N wire and flock. The foam element was never to be cleaned and reused on the AC filters because they were wetted with a special proprietery fluid, only replaced.
    The air filters on heavy construction equipment with engines that may cost $100,000 or more have pleated paper filters and may consist of three or more filter elements, one inside the other. Those barrel sized filters you see on 18 wheelers contain multiple nested paper filters. The idea of oil wetted flock filters seems plausible. Too bad it doesn't work.

    Re: K&N Air filter

    The AC filter appears to be treated with some substance; it's kinda tacky, like nearly dry paint.
