so I'm still sporting the OEM filter haha is the stock filter good enough to last me a while, or is there a point at which I need replace/upgrade my filter? I assume everyone just gets new filters for performance rather than as a need, am I correct?

This is my big 100th post yeah!

didn't someone say you have to replace the HKS filter every 10k or so?? And how much is one of those?

Okay so i see the price for a new filter is 20 or 25 bucks depending on size 150 or 200.. so how do you know which one of those you need?? the 150 or the 200?

The 200

muahah. the shroom revolution

anyone know of a place to get this product cheap. SOmeone said like 150 bucks is good?!? Seems expensive for a filter and some plastic... must be the name. Anyways, i noticed the website above didn't have our Audi, so what engine/car model for VW do i have to buy this for?

www.edoperformance.com

airinx shroom filters for under around $50. dope.

It doesn't show a picture and doesn't really describe what it all comes with. Maybe ebay might be the best option....

My 2 cents ......................
Personally i vill never put shroom filter in my car after seeing results of test how accurately they filter the dust..[:@]

I got a quarter for your two cents... I think someone had mentioned before on another thread that the shrooms they showed were from an older generation filter. Then agian, I haven't seen a test for the newer generation either. I doubt you'll be driving through a cloud of carbon dust anytime soon.
