actually, this intake does not have a plexiglass shield like the Roush intake. This one uses the factory air box to direct flow from up front to underneath the filter like the factory box, then a seal against the underside of the hood to prevent it from sucking engine bay air in from the top. No plexi.
Ah yes the plexiglass shield is a separate extra. Something to be aware of, even with the sealing of that top edge of the intake lid against the hood, there is zero place for cold air to be ingested with the hood closed. Engine heat rises against the hood where the opening in that air box intake lid is placed and the under hood air temps do not get anywhere near ambient temps when the truck is moving (that moving air is heating up as it moves through the radiator too). I have even removed the front and rear hood seal and have a different grill to improve airflow while moving and temps still remain 40 deg over ambient while truck is moving at 60mph. Just something to keep in mind if you are looking for more power vs more sound.
Ya, I believe it'll draw enough air from the factory snorkel and airbox and the seal will work well enough I won't have to worry too much about it. I can always use my sct x4 to log intake and ambient temps and see the correlation between stock and the aFe. The other intakes like Injen and K&N for sure will just suck in hot engine bay air.
