COBB 4 Bar MAP Sensor Kit - Subaru Impreza WRX (GE/GH/GR/GV) / Liberty GT (BL/BP) / Forester XT (SH) - Plastic Manifold
Most turbo Subarus come with a 2.5 or 3 bar MAP sensor, which reads accurately only up to about 148 kPa (21.5 psi) or 199 kPa (28.8 psi) of boost. This COBB kit swaps in a 4 bar sensor for accurate measurement and control at higher boost, on plastic intake manifold cars: the 2008-2014 Impreza WRX, 2005-2009 Liberty GT and Outback XT, and the Forester XT SH. It pairs a stainless-bodied sensor with an OEM-quality plug-and-play connector and a billet aluminium adapter that mounts in the factory location.
Note: A custom tune is required. For plastic intake manifold cars only (a separate COBB kit suits cast manifold cars). Installation by a professional is recommended.
Features
- Measures up to 4 bar (about 400 kPa absolute)
- Total error band under 1% of full scale (±4 kPa / ±0.6 psi)
- Response time under 1ms
- Plug-and-play OEM-quality connector on flying leads
- Black anodised billet aluminium adapter with 1/8" NPT thread and laser-etched "C" logo
- Keeps the factory sensor fault (DTC) detection
Pairs Well With
- COBB AEM High Flow Fuel Pump - Subaru Impreza WRX/STI (GE/GH/GR/GV) / WRX STI (VA) / Liberty GT (BL/BP)
- COBB NexGen Flex Fuel Upgrade Kit - Subaru Impreza WRX/STI (GE/GH/GR/GV) / WRX STI (VA) - Module and Harness
