    We can install the display in an OEM vent to make your install even easier… And you’ll keep your AC!

    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.
