Description
Reduces Aerodynamic Drag. The surrounding air pressure prevents your car from unleashing its real driving potential. To reduce the air pressure that flows underneath your vehicle, it’s best to equip it with this Satin Black Air Design Rear Valance Diffuser. With this accessory, your car will have less aerodynamic drag, allowing its tires to firmly grip the ground surface, so you can accelerate at a faster rate. Plus, with this diffuser installed, you can let your car show-off a sportier look.
Sturdy Polyurethane Construction. This rear valance diffuser is constructed using sturdy polyurethane material. Though polyurethane is a type of plastic, it is actually a tough and rigid material, enabling your new diffuser to withstand minor impacts. Plus, its satin black finish helps protect it from corrosive elements, allowing it to maintain its pristine condition for a long time.
Simple Installation. If you are geared with the right tools and skills, you can install this rear valance diffuser even on your own. For your convenience, this diffuser is pre-applied with 3M adhesive and comes with all the needed hardware. However, please note that the installation requires some minor drilling, so you can securely mount it to your car’s rear.
Warranty. For the customer’s assurance and protection, this product is backed by a 3-year/36,000-mile warranty whichever comes first. For more warranty information, you may check out Air Design’s official website.
Application. This Satin Black Air Design Rear Valance Diffuser is specifically designed to fit 2015-2017 GT and EcoBoost Mustangs equipped with the factory Premium Chassis Packages only (Trim Levels: 200A/201A/400A/401A). Intended for use with aftermarket quad exhaust systems.
Please Read. If you are having trouble determining what style bumper your Mustang is equipped with please refer to the comparison image above.
