The NoBuzzÖ fittings eliminate the vibration and noise of boost gauges when installed on automobiles with turbocharged engines.Mechanical boost gauges use a feed line from the turbocharger to directly measure boost pressure. A gauge vibration can occur because the air from a turbocharger comes out in high frequency air pulses that can cause the gauge to rattle or buzz. This noise can be eliminated by splicing a restrictor into the boost gauge feed line. The NoBuzzÖ T-fitting has a restrictor orifice, designed to gauge manufacturers' specifications, integrated into its feed arm. This design simplifies installation, gives a clean look, eliminates multiple points of failure with using an add-on restrictor, and retains boost gauge response time as compared to other solutions such as add-on, in-line fuel filters. The Mk5 NoBuzzÖ T-fitting kit for 2.0T FSI engines is sold individually below or is included as part of NewSouth's TurboPodÖ kits for 2.0T FSI engines.
