Volkswagen VW Golf Mk4/Bora/Jetta (1997-2004) P3 Analog/Analogue Boost & Vacuum Gauge, Manifold/Charge Pressure, 12V Voltmeter, 0-5V Sensor Inputs (AFR, Oil/Fuel Pressure) Engine Monitoring Display

P3 Analogue Multi-Function Gauge for VW Golf Mk4 and Bora 1997 to 2004 gives you rock solid turbo pressure monitoring, intake vacuum readings and live 12V system voltage, plus two auxiliary 0 to 5V channels for external sensors. It is a tidy, reliable way to keep an eye on engine vitals on both standard and tuned cars across the Mk4 platform.

We run this gauge ourselves at MJ Modifications and our customers rate it highly for its stable data, easy setup and quality build. If you want a clean cockpit solution for manifold pressure and electrical health with room to add extra sensor feeds, this unit delivers.

What it monitors

• Turbo pressure and vacuum via the dedicated analogue boost input. A boost tap is not included.
• Charging system voltage for quick battery and alternator checks.
• Two auxiliary 0 to 5V inputs for linear-output sensors such as wideband lambda controllers, oil pressure transducers, fuel pressure senders or other compatible devices.
• Optional auto-dim trigger for night driving when linked to a headlamp live.

Why enthusiasts choose this display

• Accurate manifold pressure tracking for remapped, turbocharged or naturally aspirated setups.
• Expandable sensor capability with twin analogue channels to show the readings that matter to your build.
• Straightforward wiring with clearly labelled power, ground and input leads.
• OEM-plus usability with dimming control for comfortable night-time viewing.

Perfect for

• VW Golf Mk4 and Bora owners from 1997 to 2004 who want dependable manifold pressure and voltage feedback.
• Drivers who need a compact display that can also show auxiliary sensor data through 0 to 5V signals.
• Daily use, spirited road driving and monitoring after a remap or hardware upgrade.

Installation

This is not a plug and play product. You will need to run a boost or vacuum line to the engine and complete wiring for power, ground and any optional 0 to 5V inputs. The auto-dim feature requires a connection to a headlamp live. A boost tap is not included.
