Zeitronix MAP, Boost Sensor, 75 PSI (5 Bar) absolute pressure.
This means vacuum and 60.5 PSI gauge at sea level.
Military grade sensor with unprecedented accuracy, also used in nuclear applications.

Not being happy with available on the market MAP sensors we adopted this great sensor to be used as a MAP sensor for precise manifold vacuum and boost display and logging.
Less expensive than most peak and hold boost gauges. Connecting harness and hose barb included.
