So as I keep looking for parts for the HD air cleaner option the more I find. All of these had a 4 inch duct coming in from the firewall to the precleaner but from there 2 bbl trucks had a 3 inch duct going to the air cleaner. Well I just found a lid on ebay for a medium duty truck with this option ant that have a 4 inch duct just to the air cleaner like the one from the cowl. So here it is. The air cleaner is like this one but I need to find a oe duct now that isn't damaged from the cowl to the precleaner. I have the other in good condition.
