AEM 150 PSIG Stainless Sensor Kit – 1/8" NPT Male with -4AN & 3/16 Adapters

The AEM 150 PSIg Stainless Pressure Sensor Kit is engineered for high-precision pressure monitoring in critical automotive systems, including oil, fuel, brake, and nitrous. Featuring a stainless steel body and gauge-style pressure reference, this sensor is ideal for performance builds that demand data accuracy and long-term durability under harsh conditions.

What Is PSIg?
Gauge-style sensors (PSIg) measure pressure relative to atmospheric pressure, reading 0 PSIg at sea level when unpressurised. These sensors are ideal for use in closed systems where vacuum readings are not required—making them perfect for fluid pressure monitoring in motorsport and street applications.

Brass vs Stainless: The Right Tool for the Job

• Brass Sensor = Ruler – Good for basic reference or gauge display

• Stainless Sensor = Caliper – Ideal for ECU calibration, data logging, and critical tuning

Key Features
