BMW Charged Air Inlet Intake Fitting for M57N & M57N2 - 45 Degree Elbow with O-ring and Steel Clip

Many people seem to loose this or toss it in the bin when stripping out the BMW from their conversion. 

The BMW Inlet Throttle Body fitting is a o-ring style with the sleep clip. This inlet is not really suitable for a silicone joiner and a hose clamp, there simply isn't anything for to stop the clamp from sliding off.
