If you have some automotive mechanical experience, the instructions were okay. IMO they were on the vague side and not specific for the Power Wagon. One step is to remove the lower grille via 7 retainers accessed from under the truck, which would be fine for a non-PW truck...but we have a winch and some of those retainers aren't really accessible. Read the instructions before you start so you have a good idea of what's going on, you'll notice several steps missing (like reassembly of headlight and grill)...
Don't try to cut steps with fender and headlight removal, we tried but quickly realized that the headlight has to come out. The new lower air box is basically molded around the headlight.
I can get more pics, do you have anything specific you're looking for? If you're wondering if it could be mated to a CAI (like S&B) it can't without some serious fab work.
Before the first hole, it's center punching the holes! That's where it's no turning back lol
I don't see any worries with airflow, it's pretty girthy. I'll keep an eye on MPG and see if there is anything to report back with.
I will say I removed a S&B cold air intake so I could install the snorkel (they're not compatible) and I feel like the throttle response is slightly more sluggish than with the CAI. I also have a Pedal Commander, so it's an easy fix.
