STILLEN Rear Diffuser for 2016-18 Nissan Altima [L33] - Matte Black
- Diffuser acts as an expansion chamber to manage the air as it exits from underneath the car
- Smoothing this transition reduces turbulence and drag improving air flow underneath the car.
- Aggressive styling sets your Nissan Maxima apart from boring stock
- 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.
- Perfect solution for disturbed by air entering from the sides and around the wheels..
- Vertical fences, called strakes, guide airflow into and out of the diffuser to maximize its efficiency.
- Most the aerodynamic magic has to happen ahead of the front axle and end after the rear axle.
Personalize the Nissan L33 sedans lower tail end of the Altima (valance) with something that isn't very smooth or stale. The Fifth 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.
