Description

The Holley EFI 112-557 is a high-air-flow throttle body engineered to enhance your engine's breathing capabilities. Constructed from fully CNC-machined 6061 billet aluminum, this throttle body features dual 52mm bores, designed to maximize airflow. It integrates seamlessly with your stock TPS and IAC sensors, simplifying the installation process. Designed for specific V8 applications, this throttle body includes all the essential vacuum ports and linkage required for a straightforward setup. The clear coat finish not only adds to the under-hood aesthetics but also provides a durable protective layer. Installation may require some manifold machining to ensure a proper port-match between the throttle body and the intake manifold. This Holley EFI throttle body is specifically designed for 1996-2001 Dodge Ram 1500, 2500, and 3500 models equipped with V8 engines. It is not compatible with Mopar V6 3.9L engines.
