Product Description

The AIRAID 200‑586 PowerAid Throttle Body Spacer is a performance bolt‑on upgrade designed for 2002–2009 Chevrolet TrailBlazer and GMC Envoy family vehicles equipped with the 4.2 L inline‑6 engine, including Ext, XL, Rainier, Ascender, Bravada, and Saab 9‑7X variants. This throttle body spacer uses AIRAID’s patented Helix Bore design to create a spiraling airflow pattern that enhances atomization of the air/fuel mixture as it enters the intake manifold, helping to improve engine efficiency and part‑throttle torque delivery in the low to mid‑RPM range.

Constructed from aircraft‑quality billet aluminum with an anodized red finish, the spacer is built for durability and reliability in performance use. Installation is straightforward and typically completed in under an hour using basic hand tools, with no cutting or drilling required. The kit includes all precision gaskets, brackets, and hardware needed for a complete fitment. Legal in all 50 states under CARB Executive Order D‑609‑3, this throttle body spacer is a clean, simple way to enhance your engine’s driveability, throttle response, and mid‑range power feel while maintaining emissions compliance and reliability.
