CTS TurboBOSS Turbo Inlet PipeFitment: Audi B9/9.5 S4, S5

Overview

CTS Turbo is proud to announce our turbo Inlet for the B9/9.5 Audi S4/S5 3.0T, following our BOSS line of Bolt-On-Speed-Solution parts.

Designed as an upgrade over our the factory and even our own high-flow turbo inlet pipe, the BOSS Turbo Inlet features a larger internal diameter while maintaining proper clearance and factory mounting locations for the PCV system and electrical harness.

We include adapters for hassle-free installation with many different turbochargers. Simply pop the required adapter into the inlet pipe and get ready to rip. The included silicone coupler makes installation with factory airbox or with CTS Turbo S4/S5 intakes a seamless process. No more guessing or buying additional adapters or couplers at extra cost!

A slotted mounting hole makes installation of the lower screw easy.
