F21 facelift 1 series BMW Rear diffuser fin extensions
If the after-market one series rear diffuser wasn't aggressive enough we have just upped the game!
Massively aggressive rear fins, looks great on the car, and completely transforms the boring standard BMW diffuser!
This has been surprisingly popluare!
You need this diffuser to go with these fins
This only fits with the aftermarket rear diffuser we sell and a handful of other brands. No, it is not the full diffuser, its just the fins. They will not fit the standard diffuser.
