Whether your 335i is highly tuned, or bone stock, you want to be assured your turbos are creating and maintaining boost. This gauge and gauge pod install cleanly into the center vent, and reads from -30 psi (vacuum) to 30 psi of boost. The gauge pod is molded out of Delrin with a UV stabilizer to ensure no fading, cracking, or drooping over time. Why use the center air vent? We chose this location as it didn't require modifying the dashboard or center console, and allows the gauge to be visible at all times. The gauge is even mounted slightly right of center to make sure your hand doesn't obstruct your view of the gauge. We've really tried to think of EVERYTHING on this kit! The gauge face itself uses graphics which we found to best fit in with the rest of the factory German BMW instrumentation, rather than the more Japanese "JDM" style gauge faces out there. And it has red/orange LED illumination to approximate the rest of the BMW gauges. Our 335i Boost Gauge Kit includes all electrical and mechanic parts required for install, and comes with very detailed instructions (with photos) to make installation as straight forward and simple as possible. The gauge gets its reading by cleanly installing a "T" fitting into one of the N54 engines intake/vacuum lines. The install is fully reversible, and takes about 1.5 hours from start to finish. Can be installed on all 3 series twin turbo models, produced in 2007, 2008, 2009, 2010 and newer. This boost gauge kit fits the following BMWs: 2007 E90 3 Series Sedan - 335i sedan 2007 E92 3 Series Coupe - 335i coupe 2007 E93 3 Series Convertible - 335i convertible
