Description

Personalize your 2013-2015 Nissan Altima with the STILLEN Rear Bumper Valance Diffuser. This aerodynamic and styling enhancement is crafted from a proprietary, durable polyurethane formula, backed by a limited lifetime warranty on materials. The matte black finish provides an aggressive look, and the diffuser comes pre-installed with 3M automotive tape, ensuring an OEM-quality attachment. Proper preparation and careful installation are recommended, and customers are advised to consult installation videos and instructions. For those unsure of their ability, professional installation by a reputable body shop is suggested, emphasizing the use of 3M adhesive prep and Wurth Clean Prep Solution. This rear diffuser is developed and manufactured in-house by STILLEN.
