What is the difference between the RS4 and the Audi S4? B/c I am about to buy a 2001 S4

 

Well the RS4 only came in europe.... The RS4 only came in an avant (actually 4 ish inches longer than an actual s4 avant). It had bigger (K04 as opposed to K03) turbos, different seats, and a bunch of little other stuff. Its faster, but the s4 has the same exact potential as it if ur modding.

 

So when I am looking to upgrade my S4, I should consider the nice RS4 parts. I want to make a horsepower gain in my S4 without torching my wallet, can anyone lend me inn on some great information for a 2001 audi s4. I pick it up Monday.

 

just do a search, there is a wealth of knowledge on this board, its all here

 

thanks
