A quick calculation tells me that it would take somewhere between 100,000Km and 200,000Km for one of those to pay for them self, and that's if I don't take into account the time/effort spent to clean them. In absence of independent test results, I don't believe a washable stainless steel mesh can filter any better than standard paper filter and I also don't believe it can be washed thoroughly and/or easily enough. Also, for that kind of money they should have included a nut on top of it :). Just my 2c.
I used K&N, but have recently switched mostly to OEM. Change them sometimes every oil change, sometimes every other, depending on how long I've run the oil and which oil I've used.
No 50 thousand K's mate.
Change oil every 5 thou. the price of the Oil filter against the price of throw away unit, yes I'm a bit anal maybe But I toss the filter everytime I change the oil. So I don't know what you pay for a K&N
We downunder pay at trade near $20 for the 138c (nice chrome one.)
If you don't believe they are any better,( the washable unit ) thats fine, but if race teams here are turning to them, and sponcership money is not a problem, one has to ask why? and I did, they are convinced of the 20 micron protection benifit.
Yes they are very similar, not the same units I'm looking at.
also differnt in the filtering surfaces, as the one I'm looking at has a multi layered discs that act as the filtering surfaces, a total breeze to clean, when I get my hands on one I'll pull it all apart and send pics
