    I'd never run a K&N filter on the road, I only use mine at the track and only when its not dusty. The first day I got it I held it up to the sun and thought, no thanks :).

    Oiled foam filters from uni filter/finer filter are very very good if you want something to look after your engine

    The results of that test aren't really surprising. You cant have the best of both worlds.

    What are these like price wise ?? Also do they filter as well as the paper ones ? I been using k&n for last 50,000 k's. Bit disheartening that article.

    gonna have to agree with greeny here. I used to race go karts on dirt with a BMC filter (same cotton material as k&n) and I would find dirt in the carby afterwards. oiled foam filters such as uni are excellent for filtering hence why they use them on trail bikes ;) they are just a tad more restrictive tho

    Well, for $80 odd bux, might be worth the change over to the unifilter. Are their any issues with these things ??? How long do they last for ??? Just gotta try to find one for my car who in Melbourne would sell them ???

    Have heard from the jap scence that they don't like K & N Filters because they are oiled and the HKS Filters in Jap Cars seem to perform alot better so eh who knows.

    I run a pod in my vn ss and seems to do ok but must be better than a ryco filter surely.

    I run a big cai intake in the front bumper and drive on a few dirt roads but anyway please see this old post as to how good a uni/finer filter works, ignore the hi-flow chicken wire. Although there is a slight performance penalty using one of those over a K&N or no filter about .05 of a second to 100 km/h (on a 5litre) but given that VZ's run a much bigger filter and most of you guys have alloytecs that don't suck as much air as a 304 then you may not have any power difference at all

    Yeh, I have to say that I noticed no performance gain with the K&N - makes a bit more inlet noise, that's about it. (not that I slung it on a dyno or anything, purely a "seat of the pants" measurement)

    Cheerz!

    I havent had any result of increased dusting using the K&N filter through oil tests as yet- got one at the lab at the moment, I will post up the result either way

    Nor did I, after having oil analysis done by Valvoline everything was fine. One thing i did do was clean and re-oil every 5000km's. Maf was always clean, so i can't imagine it really being an issue unless you are always driving on gravel. I even used the K & N on rally days in wet and dry conditions.

    I only oil mine every 40,000 k's. Yeah its interesting, its probably better to clean the k&n less as the more dirt it traps it filters better, restricting air flow, defeating the whole reason why i got the bloody thing !!!. Apparently with the Foam filters, its hard to clean out all the dirt, it gets trapped in the centre, again this could just be K&n marketing claims against the foam stuff. What is the best branded paper filter to use ? Ryco ???

    i personally dont think that paper filters work all that well as well, its quite obvious to see dirt on the filtered side of the element,

    so really its dammed if you do, dammed if you dont lol,

    Was just about to buy a K&N filter.... is there much performance gain comparing a K&N with the standard vr filter?
    Anythin else i could get? Have we got any word on those Lukey panel filters yet?
