I believe this comment/exclusion was just included on every 1-series/3-series in this group of testing, and is simply stating that the N51 engine (which is a LEV2 SULEV rated system) is excluded. As far as I can tell, these intakes are CARB certified for N54 engines.

My take anyways.

That make sense
