Hey guys I just picked up my new S4 last week and was looking around the internet for information and I found this forum. I would like to do some minor performence upgrades such as intake, exhaust, or performance chip. What companies make parts for the new S4? I had an A4 previously and I always went to Neuspeed for parts. I was on their website yesterday and found that they don't make anything for the V8 S4. Any guidance would be appreciated. This is an awsome machine.
