Cheap BMW 4 Series Side Skirt

The F32-generation 4 Series ran from 2013 to 2020 and received a facelift around 2017, which brought subtle exterior updates. Both your 2014 and a 2017 car sit within the same F32 generation, but because 2017 sits right at the facelift boundary, you should confirm with the breaker against your exact registration whether the pre-facelift and post-facelift skirts are interchangeable on your specific car. Never assume fitment without that check.

Yes, the generation is the most important factor — side skirts are designed around the platform and body structure of a specific generation. The F32-generation 4 Series (2013–2020) and the G22-generation 4 Series (2020 onwards) use entirely different side skirts that will not interchange. Always make sure the breaker's part comes from the same generation as your car.

Trim level does not change the physical mounting points on the car, but it does affect the styling of the side skirt itself — M Sport and M Sport Plus cars typically carry a more aggressive lower body kit than standard Sport or SE spec. When buying from a breaker, make sure the skirt matches the trim level your car was built with so the shape and finish align correctly; fitting a standard-spec skirt to an M Sport car, or vice versa, will look mismatched. Confirm the trim spec of the donor car with the breaker before purchasing.

Within the F32 generation, the Coupe (F32), Convertible (F33) and Gran Coupe (F36) all share the same platform, and side skirts are generally shared across these body styles within a given spec level. That said, minor fitment differences can exist, so it is worth confirming with the breaker that the part came from the same body style as your car if you want to be certain. This is especially relevant if the skirts are part of a body kit tied to a specific variant.

No, the engine has no bearing on side skirt fitment for the 4 Series — the body structure and skirt mounting are the same regardless of whether the car is a petrol, diesel or four-cylinder or six-cylinder variant. The trim level (Sport, M Sport, etc.) and the generation are what you need to match, not the engine code. Focus your search on those two factors when talking to a breaker.

The F32 generation ran until 2020, when BMW introduced the all-new G22 generation, so a 2020 4 Series could be either the final F32 or an early G22 depending on when in the year it was registered. A side skirt from an F32 (pre-2020 facelift) will not fit a G22, and the two are easy to confuse by year alone. Ask the breaker to confirm the generation of their donor car against your registration before ordering.
