The top-mounted threaded boost gauge allows the user to easily read the pressure in the system o prevent over pressurizing. GlowShift Tinted 7 Color 30 PSI Turbo Boost / Vacuum Gauge Kit - Includes Mechanical Hose & T-Fitting - Black Dial - Smoked Lens - For Car & Truck - 2-1/16' 52mm. This kit also comes standard with a 30-PSI gauge, threaded tire valve stem fitting and (4) stainless steel T-bolt clamps. Plugging this is also necessary if running a catch can setup that is open to atmosphere. Supplied with this kit is a rubber cap to plug the crank case vent port on the back of valve cover to prevent this boost from venting to atmosphere. So during normal boosting some pressure will be lost.

(7) On the initial run, be sure to have a boost gauge to check the. And the supplied line for it is 1/8' i believe and the BOV line is 3/8. If you are upgrading your car one of the best under the radar investments you can.

Note the N54 cylinder head has small ports in the intake ports that allows boost to enter into valve cover and crank case. i have the prosport boost electric gauge. Basically cut down the center of the old spring mount and right up to the frame rail in the front and rear. You'll be able to test for all leaks from the intake to the motor checking all leak points in between, including intercooler, clamped connections, diverter valves or BOV if installed, intake manifold seals, valve cover leaks any many other potential leak points. Started on it today, I will post some more detailed and how-to pics in the next few days but for now here ya go. Both testers must be installed at the same time and this allow pressure to be built up in the system without venting through the second turbo. Simply remove the air filters and mount both testers onto the aluminum pipes (2.5'). The N54 features a true twin turbo setup while the N55 receives a single twin-scroll turbo. One of the most notable differences are the turbochargers. BMWs N55 engine is found in the 2011-2015. This twin turbo Boost Leak Tester kit mounts the inlets of your MMP relocation upgraded intake. The N54 is found in 2007-2010 335i models along with the 2011-2013 335is.
