If you're running higher boost levels on your Mazdaspeed3 or Mazdaspeed6, and want to get accurate boost readings beyond 22psi, look no further than these Genuine Bosch MAP (Manifold Absolute Pressure) & IAT (Intake Air Temperature) sensors. We offer these sensors in three different pressure ratings, so you can get the ideal sensor for your build. 

3 Bar is good to 30psi

4 Bar is good to 45psi

An adapter harness is needed to run these sensors on your Mazdaspeed, but we do offer a plug and play sensor here
