Most Subarus are equipped with either a 2.5 or 3 bar 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 for accurate measurement and control.
Cobb's 4 Bar MAP Sensor for WRX/FXT/LGT/OBXT models with plastic manifolds is a plug and play solution that allows for precise measurement of pressures up to 4 Bar.
The Cobb pressure sensor itself is made up of a stainless steel body and flying leads terminated into an OEM quality connector, allowing for direct plug-and-play installation into supported Subarus.
Please Note: SENSOR ONLY, REQUIRES 1/8" NPT ADAPTER FOR INSTALL
