Smoothing out the air flow under the body of your car isn't a thought in everybody's mind. This can be important because as air moved forwards the molecules get disrupted causing a vacuum effect.  An APR Performance Rear Diffuser can help. Most people that have a Rear Diffuser on their car don't really even know what it does.  This rear diffuser will channel the high speed air flow smoothly, allowing a nice transition into low pressure.  With the use of a rear diffuser, you will allow some of your other aerodynamic components to function properly such as an aerodynamic wing, or even a spoiler.

Made from vacuum formed carbon fiber this wind splitter is light weight and extremely durable. You will find this rear diffuser easy to install with factory fit mounting design for an OEM fit.
