The Speedmaster PCE138.1005 is a 92mm high-flow throttle body designed for LS2 4-bolt intake manifold applications, delivering improved airflow over the factory unit to help maximize throttle response and overall engine performance. The aggressive black finish gives your engine bay a clean, purposeful look while the precision-bored 92mm bore supports the increased air volume demanded by built and naturally aspirated LS2-based engines.
Engineered as a direct-fit replacement for LS2 4-bolt throttle body configurations, this Speedmaster unit is a straightforward upgrade for enthusiasts looking to reduce intake restriction and support higher power output. Whether complementing a cam swap, heads upgrade, or forced induction build, the PCE138.1005 is a proven choice for serious LS performance applications.
