ECS Tuning E8x M-Sport Rear Diffuser - Textured Black

Introducing our rear diffuser designed exclusively for your 1 Series – a perfect intersection of aftermarket and factory styling. Rarely do you find a design that not only encapsulates every curve and contour of a vehicle but elevates its overall aesthetic with a single, impactful addition. There are limited aftermarket options available for the 1 Series, our engineers have risen to the challenge of providing aftermarket support for these perfectly sized vehicles starting with this one-of-a-kind rear bumper upgrade.

Our diffuser replaces the mundane factory M Sport diffuser with a perfectly fitting alternative, designed to enhance the rear end of your 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, we achieved an impressive fit and finish, but our commitment to excellence led us to make further refinements. With our updated design, the ECS diffuser is now polished to perfection, an indication of the time and effort we invest in each product.

Installation is a breeze, requiring no drilling, cutting, or modifications of any kind. Simply remove your 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.

For those with a 1 Series, anticipate a wave of excitement as we unveil a range of exhaust options tailored to all motor variants, including the N52, N54, and N55.
