P3 Gauge – VW Golf / GTI/R MK8/8.5

P3 – OBD2 Vent Multi-Gauge V3 – VW Golf / GTI / R MK8 / MK8.5

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 pressure, engine temperatures, performance timers, diagnostic reading/clearing, and more. All 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.

Gauge Modes / Readings

We designed the P3 Gauge to read the most important data from your specific vehicle for true plug-and-play installation. With a single OBD port connection, you’ll be up and running in minutes. Advanced tuners can add additional sensors or even run the gauge in analog-only mode if desired.
