Description

The STILLEN Rear Diffuser is designed to enhance the rear aesthetics of the 2009-2015 Nissan Maxima, providing an aggressive, race-inspired look. This rear bumper valance is crafted from durable polyurethane and comes painted in a matte black finish, ready for immediate installation. Installation is straightforward thanks to the pre-installed 3M automotive tape, mirroring the method used by OEM manufacturers. The design ensures no cutting or modification to the vehicle's bumper is necessary, and the diffuser is removable. The product also features oversized exhaust tip openings that beautifully frame aftermarket exhaust systems. This rear diffuser is intended to complement other STILLEN aero components, such as the Front Splitter and Side Skirts, for a cohesive aesthetic package. It can be installed with or without STILLEN Rear Corners. The product is backed by a Limited Lifetime Warranty.
