Chevrolet Suburban Throttle Body Spacer - Airaid PowerAid TB Spacer (2014–2020) is a bolt-on throttle body spacer designed to improve mid-range driveability for compatible V8 Suburban models. It uses AIRAID/PowerAid's Helix Bore technology to alter the incoming air charge for better part-throttle performance.

This spacer is engineered to enhance off-idle torque and mid-range response by spinning the intake air as it passes through the throttle body. The patented Helix Bore increases air velocity and helps with atomization of the air/fuel mixture, targeting improvements primarily between roughly 800 and 3,000 rpm. The unit ships with mounting hardware and fits 2014–2020 Chevrolet Suburban 5.3L V8 applications, offering a simple installation that retains factory connections and throttle body orientation.
