P3 Gauge - Audi A4/S4/RS4/A5/S5/RS5 (B9) 2016-2025
Custom built multi-function digital boost gauge and more for the B9 generation (2017-2024) Audi A4, S4, RS4, A5, S5, and RS5, including 35 TFSI, 40 TFSI, 45 TFSI, S4 3.0 TFSI, RS4 2.9 TFSI, 35 TDI, 40 TDI, 45 TDI, S5 3.0 TFSI, and RS5 2.9 TFSI quattro models.
Base product is for the gauge only, which will require retrofitting to your existing vent assembly. If you'd like the gauge pre-installed in an OEM vent, please select the pre-installed option.
Form and Function
Every P3 Gauge is built just for your car. It fits perfectly - like it was born there.
Stealthy. Stylish. Smart.
In one sleek display you get real-time access to everything that matters - Boost, Engine Temps, Performance Timers, Code Reading/Clearing, and more. All that from the included diagnostics port connection or optional add-on sensors.
It’s easy to install, simple to use, and made to last.
Every unit is built to order, hand-assembled, and developed entirely in-house... not by a huge corporation but by a small team who loves cars as much as you do.
