would it make a difference if you used a heat shield to block off the filter from warm air, or is the filter far enough from the engine with the g3 where you dont need one?

There filters on the Stillen Gen 3 are way out in front of the radiator, inside the upper part of the front bumper. They're not directly getting heat from the engine bay at all out there, although they probably do pick up a little heat from the radiator and/or any oil cooler.

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.

Check out my DIY for ducting. I think your on the money as far as dumping air infront of the filters. There's all that dead space in front of them, forcing all the air that supplies the car to come from behind.
