If you like our performance style carbon fiber diffuser for the BMW 4 series, but would prefer something less exensive for an option that is easier to install then this version made out of durable polypropylene is the answer for you. These diffuser are made using 100% polypropylene which is the same material as the OEM bumpers so you know they are built to last. They will fit all 2014-2020 BMW F32 coupe, F33 convertible or F36 gran coupe M Sport models. This performance style M Sport 4 series diffuser installs right where your old diffuser mounts using the same mounting locations. This makes the install very simple and can be done in under 30 minutes. Each piece is then quality checked by our team at RW Carbon to make sure you are receiving a high quality Performance Style Diffuser.
