Well, as the title suggests, APR have just released their Stage 3 supercharger kit for the B7 Audi RS4. I'm sure you will all agree it is an AMAZING looking piece of kit, with power and torque figures to match!
The kit takes the standard 414bhp engine and cranks it up to an astonishing 550bhp! All this while still using the standard intake and exhaust systems!
We are just waiting on prices for europe, but will keep you all up to date as soon as we have some!
