AEM's 3.5 Bar Stainless MAP Sensor Kit uses a stainless steel sensor body with a 1/8" NPT male thread. Absolute (PSIa) pressure sensors are referenced to absolute zero, the pressure measurement when all atmospheric pressure has been removed; the most common use is reading manifold pressure. PSIa sensors are required for measuring vacuum and will read about 14.7 PSI when exposed to atmospheric pressure at sea level, though they can be recalibrated to read zero at atmospheric pressure. This product carries a California Proposition 65 warning per the manufacturer's data.
Stainless steel sensors are the more precise option compared to brass sensors, similar to the difference between a caliper and a ruler - ideal for applications like MAP sensor data feeding ECU calibration where exact detail matters.

FAQ
What is an absolute (PSIa) pressure sensor used for?
PSIa sensors are referenced to absolute zero and are most commonly used to read manifold absolute pressure (MAP), including vacuum measurement.
What is the pressure range of this sensor?
It measures 0-50 PSIa, equivalent to 3.5 BAR.
What is included in the kit?
The kit includes the stainless MAP sensor, a 1/8" NPT to -4 AN adapter, barbed fitting, connector, and pins.
