CAP Post Throttle Valve Titanium Charge Pipe Kit for Audi B9/B9.5 S4/S5/SQ5

Post Throttle Valve Titanium Charge Pipe Kit For Audi B9 3.0T

The world’s first titanium post throttle valve charge pipe kit for the Audi B9 3.0T platform!

After extensive development on the turbocharged 3.0T engine in the B9 S4,S5 and SQ5, Can Auto Performance is proud to release a solution that eliminates one of the most overlooked factory restrictions in the system. This is not just another pipe upgrade. This is the first titanium post throttle charge pipe kit ever produced for this platform.

When you increase boost and power, airflow becomes everything. The factory post throttle piping was never designed for tuned vehicles pushing higher boost levels. Once the intercooler and main charge pipes are upgraded, this section becomes the next restriction and CAP has engineered the fix.

The Next Bottleneck Eliminated

The OEM post throttle pipes are acceptable for stock power levels. That changes immediately once the vehicle is tuned.

The small diameter and restrictive shape limit airflow and reduce throttle response under higher boost conditions. When chasing consistent power and clean power delivery, this becomes a clear weak point in the system.

Our titanium solution increases airflow, improves response, and ensures the platform can support higher power levels reliably.

Aerospace Grade Titanium Construction

This is the first titanium charge pipe kit of its kind in the world for the B9 3.0T.

Titanium offers exceptional strength while remaining lightweight. It resists corrosion, handles high boost pressures, and provides an exotic finish that stands apart from traditional aluminum options. This is performance and presence in one package.

Each pipe is mandrel bent for smooth airflow and optimized geometry to reduce turbulence and restriction.

Built To Lead In Fitment Flow And Finish

At CAP we obsess over details. This kit was engineered to lead the industry in quality, fitment, and performance.

• Mandrel bent construction for consistent airflow
