AEM 5 Bar Stainless Steel MAP Sensor Kit – 1/8" NPT Male with -4AN & 3/16 Adapters

The AEM 5 BAR MAP Sensor Kit (75 PSIg) delivers precise gauge pressure readings for high-performance applications including fuel, oil, brake, and nitrous systems. Built with a corrosion-resistant stainless steel body and engineered for accuracy within 1% of full scale, this sensor is designed for motorsport and tuning environments where reliable pressure data is critical.

What is PSIg?
This sensor measures gauge pressure (PSIg), meaning it references atmospheric pressure as zero. It will read 0 PSIg at sea level with no applied pressure, making it ideal for monitoring systems that do not require vacuum measurement. Common use cases include fuel pressure, oil pressure, brake line pressure, and nitrous bottle pressure.

Stainless vs Brass – Know the Use Case

• Brass Sensor = Ruler – Use for basic monitoring or gauge reference

• Stainless Sensor = Caliper – Use for tuning, ECU input, and critical data accuracy
