New South Performance - VW/Audi 2.0 TFSI & Audi A4 2.0 FSI NoBuzz Fitting Kit
For VW/Audi 2.0 TFSI and Audi A4 (B6/B7 Chassis) with 2.0 FSI engines.
The NoBuzz 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 NoBuzz 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.
