AEM 100 PSIG Stainless Sensor Kit – 1/8" NPT Male with -4AN & 3/16 Adapters

The AEM 100 PSIg Stainless Pressure Sensor Kit is engineered for accurate gauge pressure monitoring in vital automotive systems such as fuel, oil, brake, and nitrous. With a robust stainless steel body, high sealing integrity, and wide fluid compatibility, this sensor delivers reliable performance for motorsport, tuning, and performance street applications.

Gauge Pressure Explained
This PSIg (gauge pressure) sensor reads pressure relative to atmospheric conditions—displaying 0 PSI when exposed to ambient air at sea level. It is ideal for measuring positive pressure in closed systems, without the need to reference vacuum.

Precision vs Reference Monitoring

• Brass Sensor = Ruler – Good for casual monitoring and gauge readouts

• Stainless Sensor = Caliper – Required for precise ECU input, data logging, and tuning-critical applications
