Stillen Rear Diffuser [Matte Black] for your 2016-2018 Nissan Altima.

Personalize the Nissan L33 sedans lower tail end of the Altima (valance) with something that isn't very smooth or stale. This cosmetic piece will compliment other Nissan L33 exterior modifications, such as dual carbon fiber exhaust tips and/or track wing, with a final piece that makes it scream aggression.

This rear modification controls the air flowing underneath the vehicle and extracts the trapped air, increasing the movement of air behind the rear bumper. Adding this rear diffuser modification will complete the bottom of the L33, show casing the flow of aerodynamic pieces that are uniquely designed for the Nissan Altima L33 by Stillen.

• Widens the look creating attention to the rear bumper adding a sexy and sporty look
• Compliments the factory exhaust cut out nicely
• Works best with cars that have a rake angle
