This is the OEM MAP (Manifold Abolute Pressure) Sensor located on the upper plenum on all 2009+ Nissan GTR R35 models. The MAP sensor is responsible for providing the ECU with manifold pressure information which is used to calculate air density and determine the engines mass air flow rate. When these sensors fail the result is often poor running conditions and/or Check Engine Light Illumination.

This sensor is also compatible with VHR plenums used in the 370Z, G37 where a MAP sensor with a higher range for forced induction applications is desired.
