Make Air Intake Assembly Easier with Vibrant Performance Throttle Body Flanges and Adapters

Silicone couplers are popular for attaching air intake tubing to a throttle body. But if you’re looking to turn up the boost on a turbocharged engine, a coupler will have a tendency to pop off. In this case, an HD clamp is the way to go. It provides a more secure connection with less chance of leaking precious boost pressure. Vibrant Performance’s Throttle Body Transition Flange and Bosch DBW Throttle Body Adapters make it easy to use a clamp to keep things secure.

4-Inch HD to 4.25-Inch OD Throttle Body Transition Flange
This transition flange allows you to use a 4-inch HD clamp on 4.25-inch diameter air intake tubing or throttle body mounts. It also helps reduce movement between hard- and soft-mounted components in the air intake assembly. That reduces the chances of a coupler or clamp from vibrating loose.

Made from 6061 aluminum, the flange is CNC-machined to tight tolerances to eliminate leaks and withstand extreme boost pressure. It comes with an O-ring seal and is ready to weld out of the box.

Bosch DBW Throttle Body Adapters
Bosch makes some universal-fit Drive-by-Wire (DBW) throttle bodies that are popular with custom engine builders. They are available in larger bore sizes for extra airflow on smaller cubic inch engines, and also allow the use of boost control, throttle control, and traction control systems via an aftermarket engine management system. A DBW throttle body even lets you rev-match downshifts.

Vibrant Performance Throttle Body Adapters make it a snap to use a Vibrant 3- or 3.5-inch HD clamp to connect a 74mm or 82mm DBW throttle body to air intake tubing. That eliminates the need to weld an HD clamp adapter on the throttle body and possibly damage the electronics. CNC-machined from billet aluminum, the adapters have a dual O-ring seal design on the throttle body side for a leak-free seal even under high boost conditions.

Vibrant Performance Throttle Body Adapters come with the adapter, a green O-ring for the clamp side, two black O-rings for the throttle body side, and hardware.
