P3 Gauges Multi-Function OBD2 Digital Vent Gauge Version 3 2008-2014 WRX / 2008-2014 STI / 2008-2014 Impreza / 2008-2014 Forester

The P3 Gauges multi-Function digital vent gauge displays critical vehicle metrics like coolant temp, intake air temp, ignition timing, speed, RPM with shift light, and battery voltage - as well as peak recall in all modes.

The P3 V3 Gauge adds even more user control to what the OBD2 Multi-Gauge already offered. Read DTCs on command, remove pids that you don't care to see, configure units settings of individual measurements, calibrate your vehicle speed, read AFR in Lambda. No more bulky pillar or column pods... No more squinting to read tiny pixelated screens...  While retaining the OEM plus design that blends into your interior, the P3 V3 packs a punch with it's bold, bright display that allows you to pick up info at a glance.

Even though the P3 V3 installs in your air vent, we keep in mind that you need that heat and A/C while designing each gauge. We've torture-tested our gauges to the extreme. From frozen solid at -94 F to physically melting at hundreds of degrees, our gauges function far beyond the limits of the in-car environment.
