The APR Performance Front Wind Splitters for the Evo X front bumper for either the OEM lip or for use without the lip are designed to combat the effects of front end lift, giving extra traction and control in the front of your car. By creating a high pressure area on top of the wind splitter, high pressure air flow is restricted to flow underneath a car and with low pressure below the car, the effect of lift is reduced gaining extra traction and control.
