F32/F33/F36 4 Series
11 products
We carry F32 carbon fiber parts for the M Sport 4 Series coupe, along with the F33 convertible and F36 Gran Coupe. The range covers front splitters, M Performance-style side skirts, rear diffusers and trunk spoilers for 2014 to 2020 cars.
Most front and rear bumper parts are shared across the three bodies. Spoilers are body specific, and the coupe and the Gran Coupe each have their own. For the M4, see the F80/F82 M3/M4 page.
BMW F32/F33/F36 4 Series buying guide
Which parts fit the coupe, convertible and Gran Coupe
The M Sport front splitter is listed with the same fitment for the coupe, convertible and Gran Coupe, and so is the M Sport rear diffuser. The Gran Coupe also has a splitter and diffuser of its own. Spoilers depend on the body. The F32 coupe has an M4-style spoiler modeled on the F82 M4 and an MP-style spoiler based on BMW's M Performance accessory. The F36 gets a spoiler made for the Gran Coupe, and we have none listed for the F33 convertible.
Diffusers for the 435i and 440i
Our dual-exit diffuser is made for the 435i and 440i exhaust and is listed for all three bodies. It installs with the bolts from your original diffuser. On a 428i or 430i with the M Sport rear bumper, it can be part of a dual-exit exhaust conversion. The full range is on the 4 Series diffusers page.
Side skirts and installation
The M Performance-style side skirt extensions are listed for 3 and 4 Series M Sport cars and the F80 M3, but not for the F82 M4. Most of the splitters, skirts and M Sport diffusers need drilling. They come with predrilled holes and self-tapping screws, and we recommend having a professional install them. Everything here is real carbon fiber, so test-fit each part before you drill or paint it.
Frequently asked questions
Which spoiler fits the F36 Gran Coupe?
Get the F36 Gran Coupe spoiler. The M4-style and MP-style spoilers are listed for the F32 coupe, whose trunk lid has a different shape from the Gran Coupe's tailgate.
Does one front splitter fit all three 4 Series bodies?
Yes. The M Sport front splitter is listed with the same fitment for the coupe, convertible and Gran Coupe. We also have a splitter listed only for the F36 Gran Coupe. Both need drilling and come with predrilled holes and self-tapping screws.
Which diffuser suits a 440i?
Get the dual-exit diffuser listed for the 435i and 440i. It fits the coupe, convertible and Gran Coupe, and it installs with the bolts from your original diffuser. The general M Sport diffuser and the Gran Coupe diffuser are separate listings.
Will 4 Series parts fit an F82 M4?
No. The M4 has its own bumpers, so the M Sport splitters and diffusers won't fit it, and the M Performance-style side skirts are listed as not for the M4. You'll find M4 parts on the F80/F82 page.
