1 - 5 Bar Brass MAP Sensors By AEM

Absolute (PSIa) Brass Pressure Sensors
AEM offer high quality brass PSIa sensors in 30(2BAR), 50 (3.5BAR) and 75 (5BAR). PSIa is referenced to absolute zero. Absolute zero is the pressure measurement when all the pressure exerted by the atmosphere has been removed. The most common use for absolute pressure sensors is reading manifold pressure. PSIa sensors are required of you wish to measure vacuum. A PSIa sensor will read about 14.7 PSI when the sensing element is exposed to atmospheric pressure at sea level however they can be recalibrated to read zero at atmospheric and a negative number at values less than atmospheric pressure.

Which Pressure Sensor is right for you?

There are many different tools that can be used for measurement, but the degree of accuracy is dependent upon the tool. For example, a ruler can measure distance with a good degree of accuracy, but for a more precise measurement a caliper should be used. The difference between a brass pressure sensor and a stainless steel pressure sensor is similar if we think about it in these terms:

Brass Pressure Sensor = Ruler
Use a Brass Pressure Sensor where you need a good reference to what pressure is being seen.
Example: Brass Pressure Sensor used for a Boost Gauge Reference/Information for knowing manifold pressure, not for ECU calibration.

Stainless Pressure Sensor = Caliper
Use a SS Pressure Sensor where you need exact details of the pressure.
Example: MAP Sensor information for the ECU Calibration/crucial information for the ECU.

never ordering car parts from amazon again lol

i purchased an aem boost sensor from amazon, (not map vendor) and they sent me the gauge with the wrong sensor (150psi sensor)
purchased this in the morning, item got shipped same day and received it ultra fast
thank you map, sensor works as it should.

Fixed boost sensor

My sensor was getting stuck on -0.5 vacuum, ordered the sensor but initially ordered the wrong sensor. No worries they made it easy to return it and get the correct sensor. This new sensor fixed the problem right away. Thanks MAPerformance

Sensor

My sensor for boost gauge was shot, didn’t read vacuum. Grabbed a 3.5 BAR sensor and it worked good as new, reading like it should. Thanks MAPerformance

Perfect!

The part was received exactly as pictured and factory sealed by AEM. Fast shipping and A1 service! Perfect for my Fuel pressure and oil pressure readings on my AEM infinity ECU.

3 bar sensor

Product worked as intended. Shipping was fast. Would definitely buy from this company again. Thanks.
