4 Bar MAP Sensor and Adapter Harness for BMW N54, N55 and S55 Turbo Engines
Take your boosted BMW further with this direct-fit 4 bar MAP upgrade. Designed for remapped and high-boost builds, this sensor and adapter harness lets your engine management accurately read pressure up to around 43 psi, delivering rock-solid data for smooth power, consistent drivability and reliable logging on fast road and track cars.
We have installed this kit on multiple customer cars and our own projects at MJ Modifications. Fitment is clean, the OE-style connectors clip straight in and the scaling is stable at elevated boost levels. Owners love the factory-look install with no cutting or splicing and the confidence it gives when running bigger turbos or aggressive calibrations.
