Built for serious horsepower, the Granatelli Motorsports 105mm Drive-By-Wire Throttle Body provides the airflow capacity needed to support aggressive naturally aspirated combinations and high-boost forced induction builds. Featuring an enormous 105mm throttle opening and precision CNC-machined billet construction, this throttle body removes one of the biggest airflow restrictions found in many LS engine combinations.

Manufactured from 6061-T6 billet aluminum and finished in a durable black anodized coating, the Granatelli 105mm throttle body is built to withstand the demands of both street and race applications while delivering a clean, high-end appearance under the hood.

Unlike many oversized throttle bodies, Granatelli equips this unit with a heavy-duty, high-torque electronic motor and proprietary throttle blade design engineered to remain stable under boost pressures exceeding 25 PSI. This helps prevent unwanted throttle blade movement or forced closure during aggressive acceleration, making it an excellent choice for TVS, Whipple, Roots-style, centrifugal supercharger, and turbocharged LS applications.

Installation is straightforward thanks to its direct bolt-on design. The throttle body utilizes the factory-style late-model GM 6-pin drive-by-wire connector and is compatible with factory as well as most aftermarket intake manifolds. Granatelli also includes the necessary adapter and installation hardware for supported applications, although some intake manifolds may require a specific throttle body adapter depending on their design.

Whether you’re building a high-revving naturally aspirated LS engine or feeding a boost-hungry monster, the Granatelli 105mm DBW Throttle Body delivers the airflow, responsiveness, and reliability needed to get the most from your combination.

Note: Custom ECU tuning is recommended for heavily modified or forced induction applications to ensure proper throttle calibration, drivability, and maximum performance. Always verify intake manifold compatibility before ordering.
