P3 vent-integrated turbo pressure display for BMW 5 Series F10 F1X 550i and F10 M5

Give your twin‑turbo V8 5 Series the clean, factory-look pressure readout it deserves. The P3 unit hides neatly in the stock air vent and provides instant, accurate manifold pressure and vacuum readings using a hardwired analogue sensor rated to 80 psi. You also get peak hold memory to check maximum boost after a pull, plus an onboard voltmeter to monitor battery health. It looks OEM, reacts fast, and keeps your cabin uncluttered.

We have fitted this in-house at MJ Modifications and it is a favourite with our customers for its stealthy install, quick response and everyday reliability on both standard and tuned cars.

Key reasons enthusiasts choose this vent-mounted display

• Real-time turbo pressure and vacuum from a dedicated analogue sender for sharp, lag-free data
• Peak recall - check your maximum boost after each run at the touch of a button
• Integrated 12V voltage monitor for quick battery health checks even with the engine off
• Brightness control with manual dimmer and optional auto-dim for day and night
• Wire it how you want - constant live or ignition-switched power supported

What you receive

• Digital vent display module
• Power supply unit with integrated 80 psi analogue pressure sensor
• Vacuum hose
• Wiring harness
• Fittings and hardware

Note: A pressure reference point is required. A boost tap is not included - you will need to take a line from your intake manifold or charge pipe to the supplied hose.

Compatibility

Designed for BMW F10 and wider F1X platform 550i models and the F10 M5. Perfect for drivers who want a discreet, vent-integrated pressure display with true analogue boost and vacuum monitoring.

Installation

Hardwire to power and ground, then run the vacuum line to a suitable reference on the intake or charge system for a direct manifold pressure signal. This unit does not plug into the OBD port.

Choose the OEM vent option if you want the display pre-installed in a genuine vent housing for the easiest fit.
