Just now was
getting the info on his convoluted claim.5/10 of a second in 0-60 times?5/10 second cut from 1/4 mile times?Most of that gained in the first 5 seconds or so.
Computed out the gain would account for a 50-60 h.p. or more,much more,in order to move that cars weight off the line and to the 60 mph point in that much less time.Either it is wishful thinking and not properly tested or something fishy is going on in his calculations.
Not happening,no way,50h.p. every one would be running to get a CA box with non oem filters.
Jimmy posted the test link for filters,with the numbers.If k/n could claim gains of 50 or more h.p. and half second drops in the 0-60 run you can bet they would !

do your engine a favor,get some filters oem from autohausaz.com or germanstar.net and save your maf.and your money.

Time Slips can be misinterpeted in
a myriad of ways,driver ability,testing methods etc.
anyone that has raced long enough knows what it takes to drop half a second 0-60 and it is not an air filter.Imagine no restriction at all,put a mesh screen into your filter box and see if your times drop even a tenth.
Put it on a dyno,K/n can make claims.This guys results just don't pan out.
Drop your cars weight 300 pounds and you might see a drop of 3/10sec in the 1/4 mile,drops of 5/10 in 0-60mph are not happening with a filter change.
bone stock out of the box with a fairly proficient driver that car is capable of 13.3's at 106+,so driver inexperience at the strip most likely adds up to the disparity in time slips,not the filter.

oh, okay... just the way it was worded i thought you had actually done some rough calcs rather than just 'knowing'... i don't drive my car above 80 anyway, so i have no knowledge of such things.

Rough
calculations or knowing from racing for 40 years,logic would dictate h.p. gains of that sort are the claims of snake oil salesmen,or faulty data gathering.
He claims nearly 25h.p. gain from one aftermarket filter to another.
Anyone reading this in the future can choose whatever filter they want,just don't expect these far fetched gains to really happen and if you are real lucky it won't kill your mass air sensor.
AMG is all about the power of their hand built engines,You can bet if 50 h.p. was available from a simple air filter element.It would be supplied as part of the package when it left the amg factory in Stuttgart.

Over oiling?
That's why the dealer wont warranty the maf if you install a brand new out of the box factory oiled K/N?Or that an inordinate number of maf failures occur after installation of a factory oiled k/n?
they flow less air,they pass more dirt,they cost 5 times oem.nuf said.
ohlord
maintenance recommendations?
You may be one of the lucky ones ,like the guy who says no need to change brake fluid ever in california because of the low humidity
You can put the k/n on your own pedestal,I will continue to recommend otherwise.
thanks for the sock full of quarters

I dunno if they flow less air, but other tests have shown repeatedly that they pass more dirt (larger particles getting INSIDE your engine) and also clog up much faster than conventional paper...

I'm thinking of going back to paper because of the dirt concerns. Anybody want to buy a pair of K&N?

'04 Silverado Z71 - sold all my Benzes and need another!
I didn't use them but I also have a pair of those foam RENNtech filters that came with my airbox. They look crappy and really cheap but does anyone have any info on them? I don't know if they're any good but they look to cheap for me to use, lol...
