  • 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.
  • Includes precision-cut gaskets, high-quality hardware, and application-specific brackets to ensure a perfect fit and reliable seal.
  • True bolt-on upgrade that installs in under an hour with common hand tools. No drilling, cutting, or modifications required, making it one of the easiest performance add-ons you can install.

Description

The AIRAID Throttle Body Spacer is engineered to increase off-idle torque from roughly 800 rpm up to 3,000 rpm. Its patented Helix Bore design creates a spinning airflow as it moves through the spacer, boosting air velocity and improving atomization of the air/fuel mixture before it enters the combustion chamber. The result is enhanced part-throttle torque and stronger mid-range power.
