SKU NWD-EVE200-557


The POWERAID Throttle Body Spacer was developed to enhance your vehicle's off-idle to mid-range performance and efficiency. The unique "Helix Bore" design of the POWERAID spacer creates a spinning action of the incoming air. As air passes through your throttle body, this helical effect causes the air molecules to organize and maintain high velocity.

The organization and high velocity of the air is extremely beneficial because it helps to provide a superior atomized mixture of fuel and air all the way into the combustion chamber.
