Ok so I'm looking to hear if anyone has any info. The M56 SULEV engine has a hydrocarbon filter built into the air box as a part of the emissions system. This to me says "restriction" removing it would be simple enough however would mean you can not replace it in the future if needed. The one in my vehicle is clogged and needs replaced or removed, however you can't simply walk into auto zone and buy one in fact I can't find one anywhere and fear you would need to replace the air box entirely. Not going to happen. I'm also looking at just building a short ram intake and throwing a conical filter on it, but fear it may throw a code due to the retarded emissions systems. Any advice?
