Just picked up 2001 A4 1.8t

Hey guys, I just picked up this 2001 Audi A4 1.8tqm for $7,000. The only mods it has on it right now is a giac chip, 710n diverter valve, debadged, valeo headlights, and a reiger front bumper. I want to do a couple mods to both the exterior and engine. I am thinking about doing the DIY airbox mod and possibly a boost gauge. As far as the exterior goes, right now the wheels are stock sport package painted in a gunmetal color. I would really like to find some s4 wheels (17" or 18") for a good price. I also want to put either a stock or s4 front bumper because i don't really like the reiger thats on it now and i am concerned with the reiger being too low to the ground and getting scraped up. I know I need to paint the lowers but have not seen many red A4's with painted lowers so if anybody can post a pic of what it would look like, I would appreciate it.

So what do you guys think of the car and my plans for future mods?

i just bought a 2001 a4 1.8t two days ago. Mine is all stock the only thing changed on it is its debadged
