Stealth Vent Gauge Upgrade for BMW 3 Series E9X 2006 to 2007

Looking for a factory-look pressure readout that belongs in a BMW interior? This vent-integrated pressure display is a discreet, louvre-mounted solution for the 2006 and 2007 BMW 3 Series E9X platform E90 saloon, E91 touring, E92 coupe and E93 convertible. It delivers lag-free manifold pressure and vacuum data using a direct analog sender, plus peak hold memory and a handy voltage monitor, all while keeping your cabin clean and OEM in appearance.

This setup is a wired-in, standalone analog system with an 80 psi range. It does not use the diagnostic port, CANbus or OBD connection. For drivers who prefer a diagnostic-port display, ask us about our OBD multi-gauge alternatives.
