Cowl Air Cleaner

[Unreal]

The guy I bought my original from, also had an NOS one with the ridge (still in the box, but I never checked for a date code. It had the radiused 90* elbow like the pic above. Can't speak to the notch, as I was not educated enough to know about it. (thanks to Rick, I learned a little more)

Here's an old discussion from Camaros.net ~with pictures~ just about ZL2 cowl air cleaners. http://www.camaros.net/forums/showthread.php?t=54696

Thanks John. Yes, I wrote that article quite a while ago and it was used in the Chevy punch magazine. This air cleaner is the 70 Chevelle one from that article. Since then I was educated about the notch in the snorkle. This air cleaner does not have the notch, but all other signs are correct for a factory GM air cleaner. I'm still trying to figure this one out. Thanks though!
