I had the same idea, damn thing keeps needing work so I haven't gotten around to it though. Looked alot different in my head, but I have zero fab skills so I don't even know what mine would end up looking like. I really like the way you did yours, any chance of getting pics of the air box? I am assuming you flipped it over?

I'm making a shaker style hood scoop for my jeep I'm almost done just need to make a few more welds before testing. I just want to get some feedback on this to see if people would like to see this on the market. I'll post pics and gains soon.

Ok so the welder is still down but here are the pics of the pieces so far . I still have to cut a hole for the throttle body and weld stabilizers on bottom half. The k&n air filter will bolt between the hood scoop and the base plate. More pics will come

Wow, deja-vu. I was just reading some articles on XJ CAI's and came to the same conclusion. The majority are warm air intakes or overpriced. I was doubtful of the shaker/ ram air design on a 4x4 because of rain/mud. But, I started looking at some of the F body ram air hoods and those guys run their vechiles even without baffles in the rain and just rely on the filter to keep out water. Everything I read basically says it isnt a problem except in the worst super heavy rain...I guess the solution they use is a removable baffle of some kind, although I havent saw one. They also try to keep the filter above the hood defilade. On a side note I also read a "4.0 myths" artice by JP Mag. If memory serves they figured about a 1% increase in mileage and around a 5hp increase. Not to mention (and I will probably screw this up, but someone else can correct me) for every 5 deg drop in air temp you get another 1% increase?...Lastly, I dont know how OBD2 would like ram air very much?
There really isn't enough water ingestion to even worry about. If anything it helps cool the air charge.

Quick FYI in case this is why you are doing it: Ram air is a myth pretty much funded by dodge. There are no realizable gains with a reasonably sized ram air scoop until you reach ~200 MPH
