The P3 Analog Boost Gauge is built for Z4 E85 and E86 owners who want proper monitoring without the theatre. It reads boost, vacuum, battery voltage and two configurable 0-5V inputs - ideal for oil pressure, fuel pressure or AFR on fast-road or track-day builds.
Includes dedicated analog boost sensor (boost tap not supplied), full harness, tubing, wire taps and mounting kit. Fits cleanly into the OEM-style binnacle without drilling or trimming.
Real-time analogue readings - no lag, no menu diving, just instant needle response
Dual 0-5V inputs - monitor two additional parameters without extra gauges or wiring headaches
Z4-specific calibration - pre-set for E85/E86 vacuum and boost ranges
