DeutschTuning proudly offers CTS Turbo Charge Pipe Kit Audi S4/S5 B9 2018-2023. CTS Turbo is excited to announce the release of the B9 Audi S4/S5 3.0T TFSI charge pipe upgrade kit. Factory pipe that connects intercooler to the throttle body is made of brittle plastic. It's wise to replace it with an all-aluminum high flowing CTS Turbo charge pipe. Our 2.5" charge pipe kit will increase flow and improve the reliability of your B9 Audi S4/S5. You'll notice an increase in throttle response and a decrease in turbo lag. Two water/methanol bungs provide an easy way to install injection nozzles. 2.5" mandrel-bent aluminum piping. Billet throttle body inlet adapter. Precision CNC machined MAP sensor flange. Robust Black Powdercoated Finish. 4 ply silicon connector. Stainless Steel Clamps. 2x 1/8" NPT Water-Methanol Bungs with plugs. Compatible with factory and CTS Turbo intercoolers (may be compatible with other aftermarket intercoolers).
