    Developed to enhance off-idle torque from 800 rpm to approximately 3,000 rpm,  Helix Bore design spins the incoming air charge as it passes through the throttle body spacer. This spinning 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, improved mid-range power, and overall combustion efficiency for better fuel economy.
