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!

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.

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

Dramatic exits come standard with this carbon fiber upgrade. The multi-piece Dinan rear diffuser spotlights the rear of the car and creates a new "floor" that visually appears to make the vehicle lower and more aggressive. Despite the diffuser encompassing the exhaust exits, great care was taken to ensure enough room was supplied to accommodate even large tipped exhausts, like Dinan's own. Additionally, the diffuser adds wrap arounds to each of the rear quarters that allows a harmonious and uniform visual continuation with the Dinan front lip and side skirts for a perfectly matched cosmetic solution. Features: 2x2 gloss twill carbon fiber manufactured to be impact resistant, durable and strong Clear coated for maximum UV protection and fade resistance Includes 3M double sided tape and mounting screws for easy installation with a clean fit and finish

Carbon fiber is a staple in the performance world and has been incorporated into motorsports since the early 80s. Over time companies have taken it upon themselves to create new carbon products to add to your car that may have not been originally available. Autotecknic is no different. If you're looking for a carbon addition that has been made to the highest standards with premium materials, then Autotecknic's line of carbon additions is your one-stop shop. Add some carbon to your M-Performance rear valance! Dry carbon fiber's name comes from its manufacturing process. Dry carbon fiber is formed by using a "pre-preg" or impregnated piece of carbon materials. This piece of carbon is first placed into a mold and then into a sealed autoclave to cure properly. This method creates the least amount of waste and forms a lighter version of carbon than the “wet” method. The autoclave vacuuming process of making dry carbon means fewer pinholes and virtually no air pockets in the carbon. Dry carbon is the highest-quality version of carbon fiber products that are produced.

Rather than replace the full diffuser and have potential fitment challenges with various exhaust options Dinan has opted to retain the factory gloss black lower portion of the diffuser and only replace the upper diffuser surround with a carbon fiber accent piece. This solution not only guarantees the carbon cosmetics will always play well with any personalization of the exhaust that is adopted but also offers an economical option compared to much pricier alternatives. Together with the Dinan Rear Side Splitters, the combination creates a "full" rear diffuser that is restrained but elevated and creates a nuanced OEM+ option for the marketplace. Features: 2x2 gloss twill dry carbon fiber (pre-preg) manufactured to be impact-resistant, durable, and strong Clear-coated for maximum UV protection and fade resistance Utilizes factory mounting tabs for an easy installation with a clean fit and finish Pair together with the Dinan Rear Side Splitters to complete the full rear look
