Description Reviews The R56 MINI does not come equipped with a boost gauge to monitor boost levels in their S and JCW models. NM engineering has a solution to this dilemma. The OEM intake manifold does not have a port to easily access. In order get a boost or vacuum reading, it would require drilling and tapping a hole in the intake manifold. NM Engineering's Boost Sensor Tap installs simply. Remove the OE map sensor from the intake manifold, install the NM Eng. Boost Sensor Tap in its place and reinstall your OE map sensor onto the adapter. Finish: Anodized NM Blue 1 Review 5 awesome product Posted by Unknown on 6th Jan 2015 Easy install nice quality!
