Looking to go above 45 psi in your BMW-powered vehicle? Looking for a plug-and-play solution? We have you covered with our BMW 5 bar sensor. These will allow 58 psi to be read and are factory plug, and play. Simply remove your old sensor, replace it with the 5 bar, and have your tuner rescale your map values in both your DME tune and your PI tune if applicable. These are GENUINE BMW sensors directly from BMW.
