Part #: APR - AB - 820519. Diffusers team up with a car's other aerodynamic parts to generate downforce. As a car moves forward, it displaces air, disrupting air molecules at the rear and creating a low - pressure air vacuum. This diffuser channels the high - speed airflow from beneath the car and smoothly redirects it into the rear's low - pressure area. This results in a smoother airflow under the car, enhancing the performance of other aerodynamic components like wings.
Using this rear diffuser is straightforward. Just have it properly installed on your Subaru WRX or STI from 2002 - 2007. Make sure to follow the installation instructions carefully to ensure a good fit. When driving, you'll notice improved stability and performance. As for maintenance, regularly clean the diffuser with a mild car cleaner. Avoid using harsh chemicals that could damage the carbon fiber. Check for any signs of wear or damage after long drives or rough roads. If you spot any issues, get them fixed right away to keep your diffuser working well.
