LS Billet 102mm TB Black

The LS Billet 102mm TB Black throttle body from TOP STREET PERFORMANCE is engineered for precision engine tuning and high-performance vehicle applications. Designed for enthusiasts and professional technicians who demand tight tolerances and reliable airflow control, this billet aluminum component represents a significant upgrade over factory cast units. Whether you're building a competition engine or optimizing daily-driver performance, a quality throttle body serves as the critical gateway controlling air intake volume and engine response characteristics.

Manufactured from billet aluminum, the LS Billet 102mm TB Black delivers superior dimensional accuracy and durability compared to cast alternatives, with tighter bore tolerances that minimize air leakage and maximize throttle responsiveness. The 102mm bore diameter is optimized for LS platform engines, providing the flow characteristics necessary for both naturally aspirated and forced-induction applications. At 2.75 lbs and measuring 5.5 x 3.75 x 8 inches, this throttle body integrates seamlessly into existing intake manifold configurations while the precision machining ensures smooth throttle blade operation and consistent fuel-air mixture control across the entire RPM range.

LS platform builders—including street performance, road race, and drag racing competitors—benefit from the TB Black's ability to support aggressive tuning without sacrificing reliability or throttle response linearity. Installation requires standard intake manifold bolts and basic hand tools; compatibility depends on your specific LS variant and intake manifold design. TOP STREET PERFORMANCE's billet construction resists warping and corrosion, making this throttle body a lasting investment in engine efficiency and driver control for serious performance platforms.
