P3 Cars V3 OBD2 Vent Gauge for Volkswagen Golf Mk5/GTI (2007-2009) - OEM Fit Digital Boost & Multi-Function Gauge, Plug & Play

P3 Cars V3 Vent Display for Volkswagen Golf Mk5 and GTI 2007 to 2009

Transform your Mk5 cockpit with a factory-look digital performance monitor that hides in plain sight. The P3 Cars V3 vent-mounted display integrates into the original dashboard air outlet and keeps full HVAC airflow, while delivering live engine data from the vehicle’s CAN bus via the OBD-II diagnostic socket. Expect crisp real-time readouts for turbo pressure, coolant temp, intake temps, RPM and plenty more. It is a clean, stealthy upgrade that suits daily drivers and tuned cars alike.

Simple plug-in installation at the OBD port means no cutting, no tapping and no splicing. If you want a sleek in-vent gauge solution that looks like it left the factory that way, this is the one.

Key reasons enthusiasts choose this in-vent display

• Quick install - plug into the diagnostic port and you are up and running in minutes
