The throttle body is made from high-quality billet aluminum, which is lightweight and durable. It is also CNC-machined for precision and accuracy. The throttle body is fully EFI compatible and can be used with both stock and aftermarket engine management systems. It also features a 2-piece throttle plate design, which allows for easy adjustment of the throttle plate gap for optimal performance.
The throttle body is also equipped with a 4-barrel style throttle body spacer, which provides additional clearance for aftermarket intake manifolds. The throttle body also includes a throttle position sensor (TPS) relocation bracket, which allows for easy installation of aftermarket TPS sensors.
The throttle body is also easy to install, with simple bolt-on installation. It also includes all necessary hardware, including bolts, gaskets, and throttle cable, for a hassle-free installation. This throttle body is a must-have for any LS engine enthusiast looking to improve their engine's performance and throttle response.
