Forge
The Forge Motorsport swirl flap bungs can be used to replace the problematic OE swirl flaps in your BMW. The screws holding the OE swirl flaps can work loose and fall into the engine coursing major damage. Replacing the flaps with bungs is an easy and cost effective way to stop this from happening.
Please note you will require 1 bung per cylinder. (4 cylinder engines will require 4 bungs, 6 cylinder engines will require 6 bungs). The size of the bungs required can vary from 22mm or 32mm. Please check which size you require before ordering.
