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 or ifice, 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 inline fitting, used in our DieselPod kit, is designed to be spliced into the boost gauge feed tubing and can easily retrofitted to existing boost gauge installations.
