P3 Analog/Analogue Vent-Mounted Boost & Vacuum Gauge for BMW Z4 E89 (2009-2016) - OEM Look Air Vent Pod Kit, MAP/Manifold Pressure Meter, 0-5V Sensor Inputs, 12V Battery Voltage Display, Fits Turbo & NA

P3 analogue vent display for BMW Z4 E89 2009 to 2016

Keep your BMW Z4 E89 looking factory fresh while monitoring vital engine data with this vent-mounted P3 analogue display. It sits neatly in the air vent for a stealth, OEM-style fit and gives rapid, stable readings for manifold pressure, vacuum and more. Our workshop has used this unit extensively and customers love the clean integration, fast response and premium finish that suits the E89 interior perfectly.

Why enthusiasts choose this vent-mounted display

• Manifold pressure and vacuum via the dedicated pressure transducer for clear intake pressure tracking.
• Two spare 0 to 5 volt analogue channels to show data from external senders.
• 12 V system voltage readout to keep an eye on battery health and charging performance.
• Auto dim input for comfortable night driving when linked to the headlamp circuit.
• Factory-match appearance that blends into the Z4 cabin without extra pods or clutter.
• Smooth filtering and quick updates for confident road, track day and dyno use.

Perfect for both turbo and naturally aspirated setups

Whether your E89 is turbocharged or naturally aspirated, this unit is a brilliant way to view intake pressure and auxiliary sensor data. For tuned and remapped cars it makes dialing in target pressure straightforward. For NA engines it is a powerful diagnostic tool for vacuum and general health checks.

Wiring and inputs

• Analogue pressure sensor: yellow, purple, black to the dedicated transducer. Boost tap not included.
• Analogue input 1: brown wire accepts any linear 0 to 5 V output.
• Analogue input 2: blue wire accepts any linear 0 to 5 V output.
• System voltage: red and black to power and ground.
• Optional dimming: green wire to a circuit that powers with the headlamps, then enable in the menu.

Popular 0 to 5 V sensor options

Add the data you care about and display it right in your vent. Typical uses include oil pressure, fuel pressure, coolant temperature, intake air or intercooler temperature, ethanol content and wideband lambda, provided the sender outputs a linear 0 to 5 V signal.

What is included

• Integrated vent display module
• Analogue Box control unit
• Main harness
• Hard wire harness
• Analogue pressure sensor - boost tap not included
