Did a little more digging:
It might be possible, but we would possibly need to relocate the Power steering pump reservoir.
Plus this looks like an Airbox for a 2.5l engine, might have to look at Intake hose placement and Diameter size.
Parts List:
Upper Airbox cover
Lower Airbox
Euro K&N filter
Power Steering Relocation??
This post is about updating the EURO Airbox to BMW Performance.
