Hey everyone I'm looking into purchasing a intake for my 04 S4. Does anyone know which one brings the biggest performance upgrade? I was looking into the Carborino and Stratmosphere. If anyone has any experience w/ either of these products or another intake they know of let me know...Thanks =)

It was great. I noticed a difference in torque, and a more satisfying, throaty sound. Sounded like a exhaust upgrade.

V8

is really nice, but the stock air box is quite effective, so don't expect any appreciable gains over it. Have a look at these dyno results:

I think this is probably the only true CAI on the market for the 4.2

Does anyone here have one? I know they are pricey but I figure someone has one.
