True forced induction hood scoop
So I came up with this idea a while ago because the only kits I've seen are not really cold air intakes and cost way too much. 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.

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?

Dunno how feasable it is to stop on the Hway and unbolt anything. I know a few fellas with WS6 Trans Ams that have a pretty simple cables running to their baffles. It would have to be easier to fab something like that up in an XJ too.

Agreed. Some type of blocker/baffle would be good. or at least some kind of plate that could just be slid in to block the rain
