K and N backs up their MAFS damage claims
 

Any dealer that claims your MAFS is damaged due to a K and N product they claim will back you up 100%....hmmmmm...

Good to know.

does anyone here use a K&n?

when drop in filters and intakes come available...yes, they will.

WOW now that's a company on the up-and-up. Makes me want to buy something from them.

stand up company no doubt....

agree with both of you guys, they need more companies like this..

hmmm, I was hoping that apexi would make drop in filters, but it looks like they never have... I've used k&n filters on all my cars, only one it did sort of adversely affect was my 350z, made the idle rough, but a wiring kit solved it...

I was going to get some sort of dry air filter replacement, but now I might actually just get a couple of drop in filters for my G37S, and put the paper ones in when I go to the dealer for service. :driving:
