The AIRAID Throttle Body Spacer is engineered to boost off-idle torque between 800 and 3,000 RPM. Its innovative Helix Bore design creates a spinning action for incoming air, enhancing its velocity and promoting better atomization of the air/fuel mixture as it enters the combustion chamber. This results in increased part-throttle torque and improved mid-range power, making it an excellent addition for those looking to optimize their vehicle's performance.
This throttle body spacer is crafted from high-quality billet aluminum, ensuring durability and longevity. The anodized red finish not only enhances its aesthetic appeal but also provides added protection against corrosion. With a CARB EO number of D-609-3, it meets strict emissions regulations, making it a compliant choice for California residents.
The AIRAID AIR-300-577 Throttle Body Spacer is designed to fit a wide range of vehicles, ensuring compatibility and ease of installation. Included in the package are all necessary gaskets and mounting hardware, allowing for a straightforward setup without the need for additional parts.

"This spacer really delivers on its promises. The torque increase is noticeable, especially when accelerating from a stop. Highly recommend it for anyone looking to enhance their vehicle's performance!"
"I was skeptical at first, but this throttle body spacer has made a significant impact on my car's performance. The added torque is perfect for city driving and highway merges. Worth every penny!"
