Rear Diffuser for BMW 3 Series E36 (1992-1998)

ECS Exclusive Proudly Offered at Turner Motorsport!

Add-on diffuser to deliver a true motorsport look to your M3. Fastened seamlessly to the bottom of the rear bumper giving a platform to show off your exhaust and complete the rear end of the E36.

The E36 M3 is an amazing looking car right out of the box but a common BMW issue is the height of the front vs rear bumpers. As far back as the E30, the front bumper is much lower than the rear bumper and the E36 M3 faces the same issue. With this problem the front bumper is always super low to the ground and the rear bumper looks in-complete. The ECS add-on diffuser is a unique option for balancing out the rear bumper with the height of the front bumper for a full and complete look.

Give your M3 that wild style that stands out from the crowd, and obtain a nice balanced look. This is just the start of a new line of Street Flow Diffusers diffusers that are a must have extension of your awesome ride. The diffusers come powder coated in a sleek satin-black finish, are a blast to install and fit seamlessly against the rear bumper for a professional looking install every time. The Street Flow diffuser attaches below your factory rear diffuser and exhaust of your choosing to fill out the rear end for a nice full and aggressive styling profile.

Lets take a trip together down a new and unique path. Over the years ECS has designed factory replacement ABS and Carbon Fiber diffusers for all different models of BMW's. For the factory replacements ECS focus was to take the oem characteristics and add a twist and really bring out a more aggressive look with a direct replacement diffuser. For their new line of diffusers, us as car enthusiasts wanted to design a set of diffusers that really pushed the envelope and stepped outside of our comfort zone. Our new line of add-on diffusers is a result of our engineering team and fellow enthusiasts spending time study the M3 chassis, modeling different designs, testing prototypes and making changes to get a final product that we are extremely excited to offer. The E36 M3 Street Flow Diffuser is the first in our line of new diffusers. Stay tuned for the E92 M3 diffusers next!

E36 M3 Street Flow Rear Diffuser

The E36 M3 has always been a head-turner, but the rear bumper often lacks the levelled look of the front. With BMW's signature design featuring a lower front bumper compared to the rear—an aesthetic seen across generations—this diffuser brings balance by matching the rear bumper’s height to the front, giving your lowered E36 M3 a sleek, grounded look.

Designed to add a bold edge to your M3, the Street Flow Diffuser is our latest innovation in aggressive styling, specially crafted to bridge the gap between factory lines and custom flair. Each piece is precision-engineered and powder-coated in satin black to perfectly complement the M3's factory trim. Easy to install, the diffuser seamlessly mounts to the rear bumper, ensuring a flawless fit and professional look.

The Street Flow Diffuser is a new venture for Turner Motorsport, diverging from our line of factory-replacement ABS and Carbon Fiber diffusers to deliver a design that pushes the boundaries. After extensive modeling and prototyping, we’re thrilled to debut this product, with more designs in the pipeline. Get ready to take your E36 M3 down a unique path in styling evolution.
