The Vibrant Performance 12474 throttle body adapter is designed to connect a 102 mm GM LS-series drive-by-cable throttle body to a 4-inch intake or charge-air tube. This adapter provides a practical solution for custom intake, induction, and performance engine applications where a reliable transition between throttle body and tubing is required. Its application-specific design supports clean installation and helps simplify fabrication on compatible LS-series builds.
The adapter is manufactured from aluminum for a combination of strength, low weight, and corrosion resistance. A black anodized finish adds durability and provides a clean appearance suitable for engine compartments and custom performance systems. The 4-inch connection is intended for use with compatible tubing and couplers, while the throttle body side is designed for a 102 mm GM LS drive-by-cable throttle body.
Installation is supported by the included O-ring and hardware, helping provide a secure connection and dependable sealing when properly fitted. Verify throttle body compatibility, mounting configuration, and intake system requirements before installation. The Vibrant Performance 12474 is sold individually and is a suitable choice for builders developing custom LS-series induction systems, engine swaps, and high-performance street or competition vehicles.
