P3Cars Vent Pod Boost Gauge (Analog/Analogue) for

P3 analogue pressure display for Audi B8 A4, A5, S4, S5, Q5 2008 to 2016

Transform your B8 platform cockpit with a discreet, factory-style pressure and sensor monitor that delivers rapid, reliable data for tuned and standard cars alike. This P3 unit gives you precise turbo pressure and manifold vacuum readings, a clear 12V system voltage readout, plus two auxiliary 0 to 5 volt inputs for extra sensors. Ideal for remapped 2.0 TFSI and supercharged 3.0 TFSI owners who want clean integration, quick response and rock-solid accuracy without a cluttered dash.

We run this on our own builds at MJ Modifications and customer feedback has been outstanding for clarity, stability and day-to-day usability. If you are chasing dependable manifold pressure information, an easy voltmeter view and flexible sensor expansion, this is the upgrade that keeps your B8 feeling OEM while giving you the data you need.

What it shows

• Turbo pressure and vacuum via dedicated plug for the analogue pressure sensor wiring (yellow, purple, black) — boost tap not included
• Two external sensor channels for any linear 0 to 5 V output (brown wire = input 1, blue wire = input 2)
• Vehicle voltage from the main power and ground (red wire, black wire) to monitor the electrical system

Optional convenience

• Auto-dim using the green wire tied to a lighting circuit that is live with headlamps on, then enable within the configuration menu for comfortable night driving

Why enthusiasts choose this setup

• Fast, repeatable manifold pressure feedback for confident tuning and fault finding
• Stealth, OE-style display that keeps your interior looking clean
• Two 0 to 5 V inputs for add-ons such as oil pressure, fuel pressure, ethanol content, coolant temperature, intake temperature or wideband lambda controllers
• Simple voltage check at a glance to assess battery and charging health
• Proven on our in-house cars and trusted by our customers
