Proven in repeated testing to improve midrange power in a variety of GM trucks and SUVs (Escalade, Silverado, Sierra, and Yukon), the 200-639 throttle body spacer from AIRAID lengthens your system’s plenum to give your cylinders a greater volume of air to draw from. These throttle body spacers will increase off-idle torque from 800 to about 3,000 RPM thanks to their patented helix bore design that results in higher airflow and faster filling of each individual cylinder.
Each 200-639 spacer is constructed from aircraft-grade 6061-T6 aluminum, and every kit includes all instructions and required gaskets, hardware, and brackets to maintain geometry with factory components.
