I'm really quite confused as to whether the K&N 69 series is legal on my '09 Cobalt LS 2.2 in New Jersey. I'm looking into buying it but I don't want to end up with issues that lead me to having to take it off. A cursory look at the info sheet on the K&N website says it's not legal, but the wording of laws and all that nonsense confuses the hell out of me. So I was wondering if there was any Cobalts in New Jersey that have this intake on an '07 or newer, which the website seems to say is ILLEGAL due to emissions standards. Someone please explain.
