The POWERAID Throttle Body Spacer is designed to enhance off-idle torque from 800 rpm to approximately 3,000 rpm. The spacer utilizes it's unique, patented Helix Bore design to spin the incoming air charge as it passes through the throttle body spacer. The spinning air action boosts the velocity of the incoming air and contributes to better atomization of the air/fuel mixture as the air charge enters the combustion chamber. The end result is more part-throttle torque and improved mid-range power.
Installation Instructions

  • Constructed from 6061-T6 aircraft-grade aluminum with precision CNC machining, this spacer is engineered to deliver long-term durability and precise airflow control, even in demanding driving conditions.
  • Designed to improve low-end torque, the spacer sharpens throttle response and provides a more immediate, energetic power delivery the moment you tap the pedal.
  • Enhances mid-range horsepower for stronger acceleration during daily driving, towing, or passing on the highway, giving your engine a smoother and more consistent power curve.
