APR Performance - Ford Mustang S197 APR GTR Rear Diffuser 2005-2009 (Widebody bumper only) (AB-262020) f8x -Engine RPM-Ignition Timing-Vehicle Speed-Air FlowDiffusers work in conjunction with other aerodynamic components of a car to help produce downforce. Because a car displaces air as it moves forward, the air molecules in the rear of the car get disrupted causing a vacuum of low pressure air. To help channel the high speed air flow coming from underneath the car, diffusers redirects the high speed air flow to transition smoothly transition into the low pressure vacuum in the rear. This encourages a
