Form Meets Function

Every P3 Gauge is engineered specifically for your vehicle. Designed to replace your factory air vent, it fits seamlessly—looking like it came straight from the factory.

Stealthy. Stylish. Intelligent.

In one sleek, OEM-style display, you get real-time access to the data that matters most: boost pressure, engine temperatures, performance timers, diagnostic functions, and more. All displayed clearly without cluttering your interior.

Powerful Monitoring in a Single Display

The P3 V3 connects directly through your vehicle’s OBD2 port, giving you instant access to critical engine and performance data in minutes—no cutting, no splicing.
