STILLEN Rear Diffuser for 2016-18 Nissan Altima L33 - Unpainted Personalize the Nissan L33 sedans lower tail end of the Altima (valance) with something that isn't very smooth or stale. The 5th Gen Altimas share features similar to that of a generic soccer mom van and needs some restyling to make a standing appearance for the next event.

The factory rear valance of the L33 Altima is very bare, dead and not something you can imagine coming from an import. Upgrading it to a diffuser is something we would recommend first on any build list for exterior modifications. When adding a unique styling exterior piece to your Nissan like this, will increase the love for the car bringing back the best memories when purchasing the vessel. This cosmetic piece will compliment the rest of Nissan L33 exterior modifications of 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. Compliment the rear bumper valance diffuser with a perfect fit and beautiful sound note from the STILLEN Stainless Steel Axel-Back Exhaust System.
