Wagner Tuning Intercooler kit vs. OEM RS4 Intercooler.
There are many claims on the internet that the RS4 intercooler are the easiest upgrade for your S4 Intercooler. According to our calculations above, there is a slight increase in performance, but is it worth it?
Below are a few of the issues you will encounter for this modest performance increase:
The mounting tabs on the RS4 intercooler must be converted to the S4 style, including intercooler piping mounting differences. After you have installed the RS4 units, the engine will need to be modified to fit, as the RS4 Intercooler extend further out and cut into the cover. The S4 bumper must be modified & cut inside to fit RS4 intercooler.
The Choice is Clear - The Wagner Tuning Audi S4 / RS4 B5 Intercooler Kit not only offers higher performance, but easy installation!
