Hello,
Wanted to share that I changed the airfilters to (French) JR-filters about 15.000 mi. ago. They are K&N-style cottongauze.
TUV-approved for superior filtering and a 10% improved airflow over stock paper filters.
Still have to measure the improvements in an objective way (VCDS), but they give me at least the subjective impression that spooling up of the turbo's goes faster and that the responstime between putting down the throttle and take-off from standstill is noticebly reduced.

 

I have played with k & n in my Nsx supercharged and it feels faster but I think its the sound.....lol

the only filter i seen was bmc , its like a k&n filter

I never have liked K&n filters or any washable filter my opinion is they allow more air and more dust thru. I will stick to oem filters, thats just me tho.
