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, P3 kept in mind that you need that heat and A/C while designing each gauge.

Electronics in a harsh climate?

P3 torture-tested their gauges to the extreme. From frozen solid at -94 F to physically melting at hundreds of degrees, their gauges function far beyond the limits of the in-car environment.

Form, fit, function! Fantastic product!

This gauge checks all the boxes for even the most picky of owners.
Form- looks great in the car, colors for material and display are a spot-on match for OEM.
Fit- Install is smooth and fits like an OEM product. No looseness, no misalignments.
Function- Does what I wanted it to do and more. It's a great diagnostic tool for owners that self-repair but don't have access to high-end scan tools.
PRL hit this one out of the park. Great job.

Love these gauges!!

This was one of the easiest mod's I've done so far! They look almost like a factory install. I'm really glad I got to keep 2 of the air vents and not lose them all. The gauges match the cars factory gauge colors perfectly. I could not be more happy with them!

P3 Gauges 2018+ Honda Accord OBD2 Vent Gauge V3

I really like that there is a step by step install. Took about 35 mins and really easy too. QR codes in pamphlet it comes with sends you to install, calibrate and trouble shoot videos if you have any questions. Vent still works fine and blends in just enough to make it look like a factory upgrade. You will notice the gauges reflection off your driver side window if tinted dark but still worth it. Must have if you are modifying your Accord. I like the 0 to 60 feature the most. This was an impulse buy, (“Shut up and take my money!”) kind of thing and I don’t regret it.
