Granatelli Motor Sports GMTBLS105 Billet Throttle Body GM Drive-By-Wire - 105mm LS3/LSA/LS

The Granatelli Motor Sports GMTBLS105 is a high-performance 105mm billet throttle body designed for GM LS3, LSA, and other LSx engines equipped with electronic drive-by-wire throttle control. CNC-machined from high-quality billet aluminum with a natural finish, this throttle body provides significantly increased airflow over the factory unit, making it an ideal upgrade for forced induction applications, high-performance street builds, and racing engines.

Key Features:

• 105mm bore diameter for maximum airflow and performance gains
• Precision CNC-machined from billet aluminum for durability and optimal flow characteristics
• Direct bolt-on replacement for factory GM drive-by-wire throttle bodies
• Compatible with LS3, LSA, and LSx engines with electronic throttle control
• Natural aluminum finish that can be polished or powder-coated
• Includes all necessary gaskets and hardware for installation
• Engineered to work with factory ECU and throttle position sensors

This oversized throttle body is especially beneficial for supercharged and turbocharged applications where maximizing airflow is critical to performance. The increased bore diameter reduces restriction at the intake entrance, allowing your engine to breathe more freely and produce more power. Installation is straightforward using factory mounting points and electrical connections, though ECU calibration may be required for optimal performance.
