AEM CAI and Fresh Air Entry

So I recently got an AEM CAI and now have a big decision to make. This is the CAI where the filter is located inside the bumper cavity, almost behind the driver-side triangular grill insert.

I poked around the bumper a bit and couldn't find any kind of significant opening to that area, meaning that there doesn't seem to be any kind of way for a good amount of fresh air to get to the filter. So I figure that if I want to maximize the benefit of the CAI, I'm going to have to do some modding.

What should I cut up to get some air into the bumper cavity? I do have the Echomaster DRL LEDs, so I wanted to avoid putting holes into the grille inserts, but will consider if it that's the best way to go. I could also cut part of the radiator shroud off, but that seems a less efficient way of getting air than drilling into the grille inserts. And is there a concern about water getting into that part of the bumper cavity?

Not the most proffessional looking, but back when I had Newmissions intake tube mod installed I just drilled some holes into the bottom part of the triangle there. I'll post some pictures tomorrow if I remember. With that said, I'm no engineer so I can't tell you for sure whether that actually does anything.

In your case I'd be hesitant making any cutouts. With the intake that low to begin with I'd be worried about water getting in, though I suppose you could use a pre-filter to help with that.

Anyone more professional want to chime in?

Yeah, drilling holes is one of the options I was considering - looking at the lack of ways for fresh air to get into the bumper, I figure every little hole is going to help. And if I do go ahead with it, AEM does make some nice pre-filters

I also have the AEM CAI and I removed the bottom part of the triangle. The intake is further to the right and facing back which limits the amount of water that can reach it, so I'm not overly concerned about that. A pre filter or some sort of deflector wouldn't hurt though, I'll look into that when I clean it later this month.

I would only worry about water and AEM if I had to drive though this but then again even with stock air box there is the water up the tail pipe. Before you say how reverse pulse there is an exhaust pressure which isn't much put your hand over the pipe you can close it off like stuffing a potato in the tail pipe there is also a vacuum hold a corner of tisure paper to tail pipe it will suck in mostly blow out though. This is why when I-4 flooded like this only big trucks with stacks could go though they would not let box trucks with high mufflers go.

Cool pictures guys. I'm going to hold off on any drilling since I'm pretty happy with the performance as is. Maybe when it gets hotter and if the performance is affected, I'll look back into some drilling.

Seminoles, what's your plan for the original intake tubes? Are you sealing them up?

Keep us posted on this when you get it cleaned up. This is a really good idea.
