I have a bunch of parts in my garage to do a Modshack-style ducting job to bring outside air directly to the Gen 3 filters, we'll see if it makes any difference. I don't plan on trying to seal over the filters like he did though, I'm just going to route the tubing to dump cold air right on top of them.
