You asked, we answered.

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.

There when you need it, hidden when you don’t.

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.

Hot or Cold? No problem!

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.

Electronics in a harsh climate? We’ve got that covered too.

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.
Please Note

  • The gauge does not come pre-installed in the air conditioner vent. Vent is not included.
  • We only stock gauges for Right Hand Drive vehicles
