Improve Your SUV's Performance with the Airaid PowerAid Throttle Body Spacer

Designed for the 2002-2009 Chevrolet Trailblazer and GMC Envoy models equipped with the 4.2L inline-6 engine, the Airaid PowerAid Throttle Body Spacer is engineered to deliver a noticeable increase in off-idle torque and overall engine responsiveness. This upgrade helps your SUV feel more powerful and agile, especially in everyday driving conditions.

Experience the Helix Bore Difference:

The core of the PowerAid spacer's performance enhancement lies in its unique, patented Helix Bore design. This innovative feature spins the incoming air charge as it passes through the throttle body, increasing its velocity. This controlled air spin promotes better atomization of the air-fuel mixture as it enters the combustion chamber. The result is a significant improvement in torque, particularly in the crucial 800 to 3,000 RPM range, leading to quicker acceleration from a stop and more confident merging or passing.

Key Features and Benefits:

  • Increases off-idle torque for better initial acceleration.
  • Boosts mid-range power for improved drivability.
  • Utilizes the patented Helix Bore design for optimal air spin.
  • Enhances fuel atomization for potentially better efficiency.
  • Straightforward bolt-on installation; no permanent modifications needed.
  • Specifically engineered for 2002-2009 Chevrolet Trailblazer and GMC Envoy models with the 4.2L I6 engine.
  • Also compatible with Buick Rainier, Isuzu Ascender, and Saab 9-7X models of the same era.

  • 2002-2009 Chevrolet Trailblazer (4.2L I6)
  • 2002-2009 GMC Envoy (4.2L I6)
