Rear Diffuser

The Stillen Rear Diffuser is engineered to give the 2016-2018 Nissan Altima a more aggressive, track-inspired aesthetic. It aims to enhance the overall styling of the L33 Altima, moving away from a more conventional look towards a performance-oriented stance. Crafted from durable polyurethane, this rear diffuser is pre-fitted with 3M automotive tape, ensuring a straightforward installation process similar to OEM standards. Crucially, it requires no cutting or permanent modification to the existing bumper, allowing for easy removal if desired. The unpainted finish provides a clean slate for custom painting, allowing owners to match it precisely to their vehicle's color scheme or a unique custom design. This aerodynamic function contributes to the car's performance appearance. For an even more integrated look and sound, Stillen suggests complementing the rear bumper diffuser with their Stainless Steel Axel-Back Exhaust System. This product comes with a Limited Lifetime Warranty, underscoring Stillen's commitment to quality and durability. It is specifically designed for the 2016-2018 Nissan Altima [L33] models.
