CTS TURBO B9 AUDI S4/S5 3.0T CHARGE PIPE KIT
The factory pipe connecting the intercooler to the throttle body on the B9 Audi S4/S5 3.0T TFSI is brittle plastic and a known weak point. Swap it for the all-aluminum, high-flowing CTS Turbo charge pipe. This 2.5" kit increases flow and improves reliability while sharpening throttle response and cutting turbo lag. Two water/methanol bungs make adding injection nozzles easy.
