Hello all. Great forum. Quick question.... what do you guys think is the best bang for your buck as a bolt on or upgrade for performance. I’m not lookin to go crazy but I know these cars have room for power. Also, what is the best air cleaner set up? I want to open up my air cleaner box and have the heard the sound of the turbo sounds so much better without it? New to the RS3 world and would appreciate any insight. Thanks again and happy to be part of the forum!
