The AIRAID PowerAid throttle body spacer for 1991–1995 C/K 454 TBI applications employs a patented Helix Bore to spin incoming air through the throttle body spacer, boosting air velocity and improving atomization of the air/fuel mixture. That spinning airflow helps increase off-idle torque and mid-range power. Installation is bolt-on with included mounting hardware and requires only common hand tools.
