Hi again Mike
Yeah had noticed that the BMW Performance air intake just seems to be a K&N instead of the paper filter, and a carbon fibre cover instead of the original plastic one. Strange.[/quote]
Hello, it seems we want similar things from our 325's
The carbon fibre bit I think has a larger opening to allow more airflow but I don't think that warrants the £700 price tag. The filter however fits the standard airbox, and cost me with my staff discount £50 and I have the knowledge that it is a genuine BMW part.
