82mm Throttle Body To 3in HD Clamp

The 82mm Throttle Body To 3in HD Clamp by Vibrant Performance is a precision adapter engineered for builders integrating larger throttle bodies into forced-induction and naturally aspirated engine platforms. This adapter bridges the gap between Bosch 82mm throttle bodies and standard 3-inch intake piping, making it essential for custom intake manifold construction, supercharger kits, and turbo setups where OEM throttle body sizing proves inadequate. Whether you're tuning a street car, developing a weekend warrior, or engineering a performance application, this adapter provides the robust interface your system demands.

Machined from black anodized aluminum, the 82mm Throttle Body To 3in HD Clamp combines lightweight durability with corrosion resistance in underhood environments. The adapter features an integrated O-ring seal that eliminates vacuum leaks and provides a positive pressure-tight interface between throttle body and intake tract. Hardware is included to simplify installation, and the precision-bore design maintains proper airflow velocity while accommodating the full range of throttle plate operation without binding or restriction. The anodized finish protects against oxidation and thermal cycling, preserving mechanical integrity through repeated heat cycles.

This adapter is ideal for engine builders, tuners, and enthusiasts upgrading to larger displacement Bosch throttle bodies for improved volumetric efficiency and response characteristics. It pairs seamlessly with 3-inch intake plumbing used in aftermarket manifolds, intake runners, and intercooler piping. Installation requires basic mechanical skill—simply position the adapter between the throttle body and intake tube, torque fasteners to manufacturer specification, and verify seal integrity with a smoke test. The compact 5.85 x 4.4 x 7.35-inch profile ensures clearance in tight engine bays while accommodating various bracket and accessory configurations common in modified engine compartments.
