Cobb Tuning 4-Bar MAP Sensor 2002-2007 WRX/2004-2020 STI

Most Subarus are equipped with either a 2.5 or 3 bar Manifold Absolute Pressure (MAP) sensor from the factory which allows accurate reading up to either 21.5psi or 28.8psi, respectively. For vehicles targeting boost values higher than that, an upgraded sensor is required.

The Cobb 4-Bar MAP Sensor is a direct replacement of the factory piece and allows the ECU to accurately measure increased levels of boost pressure. The COBB 4-Bar MAP Sensor will allow accurate measuring at over 40 psi of boost pressure. This is vital for cars running boost levels that are higher than the factory sensor can accurately measure. Unlike some sensors, the Cobb 4-Bar MAP sensor allows the ECU to retain its error reporting ability and will illuminate a DTC if an error is detected.

The kit includes a billet aluminum adapter, and the plug-and-play sensor.

NOTE: Custom Tuning REQUIRED to safely utilize the Cobb Subaru 4-Bar MAP Sensor. Calibration data can be found theCobb Subaru Tuning Guide.

Fits all 2002-2007 Subaru WRX, and 2004-2020 WRX STI.
