102mm LS Throttle Body Cast Aluminum

The FiTECH 102mm LS Throttle Body Cast Aluminum is a precision fuel injection component designed for GM LS-series engine swaps and custom fuel injection conversions. This multi-port injection throttle body features a 102mm bore diameter with black powder coat finish, offering OEM-quality construction for builders seeking reliable intake manifold integration without compromising flow characteristics or throttle response.

Cast aluminum construction provides the strength needed for high-boost and naturally aspirated LS applications while maintaining a lightweight footprint. The 102mm diameter matches the standard LS intake manifold opening, ensuring direct bolt-in compatibility with FiTECH EFI systems and other quality fuel injection platforms. The black powder coat protects against corrosion and engine bay heat cycling while presenting a finished appearance. Weighing 2.23 lbs, this throttle body integrates seamlessly into street, race, and off-road engine builds where fuel delivery precision and throttle linearity are critical to drivability.

This throttle body is ideal for LS engine conversions in classic muscle cars, custom trucks, and performance vehicles where modern fuel injection replaces carburetors or older fuel systems. Whether building a restomod with a crate LS engine or retrofitting an existing LS platform with electronic fuel control, the 102mm bore supports flow rates from mild 300-hp street engines through high-output 600+ hp builds. The multi-port design works with FiTECH systems that deliver superior idle quality, cold-start performance, and part-throttle response compared to carburetor alternatives.
