Show original supplier description
The DevSport Rear Diffuser offers an aerodynamic upgrade for the 2012-2015 Honda Civic Sedan FB6, including both Si and Non-Si models with the stock bumper. This redesigned 1-piece diffuser is engineered to complement existing exterior modifications, such as DevSport's Front and Side Splitters. Constructed from durable aluminum composite, the top sections are 1/4" thick to ensure rigidity and minimize distortion, while the fins and side sections are 1/8" thick. Each piece is precision CNC machined for a perfect fit and finish, and features pre-drilled holes for simplified mounting. The diffuser is finished in a smooth satin black with a UV coating to protect against the elements. Installation involves bolting the diffuser directly to the rear bumper, with assembly required for the modular center and side sections to create the final 1-piece unit. The package includes all necessary stainless black zinc hardware and black aluminum L-brackets, along with a DevSport badge. It is compatible with the 2012, 2013, 2014, and 2015 Honda Civic Sedan FB6 models.
