Presenting the ECS rear diffuser tailored exclusively for your 1 Series – a fusion of both aftermarket and factory styling. Rarely does one find a design that not only encapsulates every curve and contour of a vehicle but elevates its overall aesthetic with a single, impactful addition. Amongst the limited options available for the 1 Series, the engineers at ECS have risen to the challenge of providing aftermarket support for these perfectly sized vehicles.

The diffuser replaces the mundane factory M Sport diffuser with a perfectly fitting alternative, designed to enhance the rear end of the 1 Series. Using the existing factory hardware and tab mounting locations, a transformation is merely a few screws and a plastic trim tool away. During the prototype phase, an impressive fit and finish were achieved, but their commitment to excellence led them to make further refinements. With the updated design, the ECS diffuser is now polished to perfection, an indication of the craftsmanship invested in each product.

Installation is a breeze, requiring no drilling, cutting, or modifications of any kind. Simply remove the current valance, align the tabs, and effortlessly secure the diffuser in place using the factory mounting locations and hardware. Ensure a snug fit by verifying the alignment of all tabs, and with a gentle press, witness the tabs seamlessly click into position.
