The Macht Schnell Boost Metering Block is a bolt-on installation without the need for drilling or tapping into factory charge pipes. Comes complete with O-rings and extended-length screws for simple installation in minutes. The Boost Metering Block is essential for boost readings while on the dyno, or for connecting an analog Boost pressure/vacuum gauge on the dyno. When not in use, the included rubber cap will properly seal the port off safely.
