      Increased Airflow. The AFE Billet Throttle Body is engineered to improve engine breathing and throttle response while maintaining factory-style drivability for 2014-2026 5.3L GMC Sierra 1500 models. By increasing bore size beyond the stock 80mm design, this throttle body helps deliver more responsive acceleration and improved overall performance without requiring additional tuning.

      Construction and Appearance. Crafted with a precision-machined billet aluminum adapter and finished in raw metal, this throttle body is built for strength, accuracy, and long-term durability. The 87mm bore diameter allows increased airflow into the intake system, supporting improved power delivery and throttle sensitivity. OE compatible and comparable design standards ensure the throttle body integrates cleanly with existing components, while the billet construction provides a solid, performance-focused feel that stands out in the engine bay without appearing out of place.

      Installation. Designed as a bolt-on, direct replacement, installation is straightforward and does not require custom fabrication or tuning. Plug-and-play electronics allow the throttle body to connect directly to factory wiring, streamlining the process and reducing installation time. The adaptable design makes it well suited for installers using basic hand tools, allowing the upgrade to be completed efficiently while maintaining proper function and reliability.

      Application. This AFE Billet Throttle Body fits 2014-2026 5.3L GMC Sierra 1500 models. By improving airflow efficiency and throttle response, it enhances driving performance, sharpens engine responsiveness, and supports a more engaging driving experience while retaining factory-level integration.
