Description

The STILLEN Rear Diffuser is meticulously crafted to dramatically improve the visual appearance of your 2016-2018 Nissan Maxima's rear bumper. Its race-inspired design incorporates aggressive fins and deep air channels, providing a wider, sportier stance that highlights the rear of the car. Constructed from durable and resilient polyurethane, this rear diffuser is built for longevity. It comes unpainted, offering a blank canvas for customization. You can choose to prime and paint it to match your vehicle's color, opt for a gloss black finish, or explore other custom options like hydrographics or vinyl wraps to achieve a unique aesthetic. The diffuser installs without requiring any cutting, trimming, or permanent modifications to your Maxima's bumper. The kit includes adhesion promoter and screws for a complete and secure installation. This removable component allows for flexibility and ease of mounting. STILLEN stands behind the quality of this product with a limited lifetime warranty.
