Throtte Body Big Mouth LT 92mm GM LS 4-Bolt

The Throttle Body Big Mouth LT 92mm GM LS 4-Bolt from FAST Electronics is designed for serious LS-platform builders who demand maximum intake flow and responsive throttle control. This throttle body replaces restrictive OEM components and is suitable for naturally aspirated, turbocharged, and supercharged LS applications where airflow needs exceed factory specifications.

With its oversized 92mm bore diameter, this throttle body minimizes intake charge velocity loss and reduces pumping losses across the RPM range. The four-bolt flange mounting pattern ensures a secure, leak-free installation on compatible LS intake manifolds. Precision-machined internal passages are optimized for laminar flow characteristics, preventing turbulence that could compromise fuel atomization and cylinder-to-cylinder distribution balance.

Ideal for LS engine swaps, performance restorations, and dedicated race applications, the Throttle Body Big Mouth LT is compatible with GM LS, LS1, LS2, LS3, LS7, and LS9 engines. Its lightweight aluminum construction ensures durability without sacrificing structural rigidity or thermal stability under high-load operation. This throttle body is perfect for builders looking to enhance performance in street machines, competition engines, or stroker builds.
