AIRAID AIR-400-590 Throttle Body Spacer
The AIRAID Throttle Body Spacer is engineered to boost off-idle torque, enhancing your driving experience from 800 RPM up to around 3,000 RPM. Thanks to its unique patented Helix Bore design, this spacer creates a swirling motion in the incoming air charge as it flows through. This innovative design increases the velocity of the air, leading to improved atomization of the air-fuel mixture before it enters the combustion chamber. The result? More part-throttle torque and a noticeable enhancement in mid-range power.
