2015-2023 Mustang HDPE Rear Diffuser
Description
Take your Mustang’s rear-end styling and aerodynamics to the next level with this performance-inspired Rear Diffuser. Designed specifically for the factory Mustang rear bumper, this diffuser delivers an aggressive, track-inspired appearance while maintaining a clean and secure fit.
Installation is designed to be one of the easiest among Mustang diffuser options. Pre-positioned mounting holes and slotted attachment points utilize two existing bolts to help perfectly center the diffuser. The slotted design also allows for adjustment, giving you greater control over the final positioning and desired gap between the diffuser and rear of the vehicle.
