I actually thought about doing that, but forgot. I'll post it up and put a link on here for cross referencing.

In my '99 it doesn't seem like theres a good amount of room to run the tube straight back, also that section of the cowl grill is slatted(openings) and the passenger side is solid. I'm gonna run the intake over to that side, and hopefully make some opening/closing door for the stock intake just in case snow covering the cowl is an issue. Basically a quick pop of the hood and attaching or taking off the cover in front.

why would you run it to the other side? The only thing i can think of that would be there is the ABS module if you have one. But you have a c8.25 rear axle, so you don't have ABS. There should be plenty of room without that there.
1. it won't fit over the valve cover, and still have big enough tubing to move the req'd air
2. why? the openings are where the air gets in - you want to be as close as possible.
3. If snow is covering the hood, won't you have to clean the snow off the hood and cowl anyways to open the hood?

Dukie, I never thought of the ABS module. This might be an issue for me. I can't look at the XJ right now, but I'd have to find a different way to route the tube. I have seen them routed across to the other side, but having now seen it this way, it seems unnecessary to go to all that trouble.
Bummer.

I also get so much ice in my cowl that the defrost does not even work. Hard as hell to get it out sometimes too. Is there a spot that you can disconnect between the cowl and the box in case the holes are completely full of ice?

Got the original idea from a guy on JeepForum, so i can't take full credit, but i made my own modifications to suite my application.
I used 3" Inside Diameter PVC
I used (2) sharp 90* "street" bend pipes - they have a female end and a male end on the same pipe bend.
I needed about 6" of straight pipe - Home Depot had 2' sections cut.
For the cowl attachement i grabbed another stock air tube from the JY, and cut one end off. It fit perfectly inside the 3" pvc. I made a 3" hole in the cowl using a drill bit many times, knocked out the circle, and cleaned up the edges with an abrasive cylinder for my dremel.
I mounted the airbox inlet higher than i would have liked, partly on accident, but it worked out fine - i just trimmed some of the air filter above the pipe so it would fit.
I used black RTV to seal it up.
I used the blocking piece that is normally in front of the airbox inlet on the front clip support as the cover for the inlet - worked great and i didn't have to buy flat PVC/plastic. Again i used Black RTV to seal and 2 self tapping sheet metal screws to hold the piece in place.
Anyways...pics:




Then i took it on it's maiden voyage:

Worked VERY well - lot's of power, no issues, kept the air filter nice and dry while fording lots of mud lakes.

Try some flexible 3" tubing to get around things. 2 1/2" inside diameter is the smallest i recommend.
