This AEM 150 PSIg stainless steel sensor kit measures gauge pressure, reading 0 PSI at atmospheric pressure and rising only as pressure increases above ambient — a common setup for oil pressure, fuel pressure, brake pressure, or nitrous pressure monitoring. The stainless steel body uses a 360-degree welded wetted area that resists automotive fluids, and accuracy within 1% of full scale makes it suitable for ECU calibration input as well as gauge display.

FAQ
What does "PSIg" mean on this sensor?
PSIg is gauge pressure, measured relative to atmospheric pressure — the sensor reads 0 PSI in open air and only registers pressure above ambient, the standard setup for oil, fuel, brake, or nitrous pressure monitoring.
What's included in the kit?
The kit includes the 150 PSIg stainless steel sensor, a mating connector and pins, and a 1/8in NPT to -4 AN adapter.
Is this sensor accurate enough for ECU tuning?
Yes — the stainless steel sensor is accurate to within 1% of full scale, suitable for ECU calibration input in addition to gauge display.
