i know alot of people say B5 S4's are unreliable. im wondering if most of these things have to do with the S4's weakpoints. if one would upgrade the diverter valves to 710n's or forge ones, and upgrade the throttle body boot to the samco/apr bi pipe/ or ams one, than what would the reliability problems be like then? those seem to be the most common ones...what else is a common reliability problem relating to B5 S4's? And how reliable would the car be if one were to upgrade the two commonly known problematic things i mentioned above?

 

anyone?...

 

We talk about it all time, that's why you are not getting a response.

yes, they are pretty good if you fix the weak links.
