Bosch 3 Bar (absolute) TMAP 0281006076

As currently used on our B46 race cars. This sensor is used in the inlet manifold and fits with minor modification. Can read down to 20kpa and up to 300kpa absolute. Good for about 450whp on the B48. 

This Bosch Map is an excellent sensor for forced induction applications such as turbocharged and supercharged vehicles. 3 bar Map sensors are not intended for naturally aspirated applications. These manifold absolute pressure sensors precisely measure the absolute pressure in your intake manifold and compare it with a reference vacuum. Plus, they allow your engine management system to accurately detect inlet air temperature, as well as manifold pressure.
