Well you can use the stock tubing, use my set up, and it will all reach, if you have all your tubing in front of you I'll try lableing it the best I can so you can have a visual, the tube I was using aftermarket wasn't the ram air kit that I got with the weapon r system, it was an intake tube from Kragen, (spectre part no.?)and that fit perfectly around the rectangular square like opening on the airbox, by anyways, so stock parts, you got the square/rectang piece that attaches to the box and has the spongy tube on it, and then the parts you'll need to attach to the bottom screw are the curved horn lookin piece with an opening and there's a little piece that clips onto that in the grooves, both are the stock parts and in my picture it shows them clipped together. Now if you get underneath your car by driver fog light you'll see the screw pretty much right off, and it holds a little plastic shield on, the easiest way is to take that screw off and bend the shield out of the way so you can reach your hands in there and also put the horn piece in there, now when you attach the stock plastic piece with air tube onto the box, route the spongy tube down to the fog light, it should almost barely reach(this is why I went aftermarket, plus it was bigger tubing and didn't have holes in it from where the silencer was)now this is where you'll hoseclamp the spongy tube to the end of the horn piece(make sure you hi've it all pointed the right way first), now for mounting the hornpiece the right way.. if you notice, the horn piece has a long little screw mount on it from where the clip was that held it on from factory, and that's how it's so perfect for this, because you put it uderneath the screwhole and then put the plastic shield hole over it and screw it down. You should be good, I still have my stock parts laying around, I might take an inventory picture and detail everything a little more with the stock parts. If you have any more questions I'll answer them and I'll take pics and post if you don't quite get the wording. I have a question though, whydid you switch back to stock setup? I've noticed so much more throttle response and power with the weapon r, and even with my cai I made with my stock airbox the weapon r does the same thing, so I prettymuch convincedyself after I heard the sound from the intake( intake noise is one of my favorite noises from a car) that even if it felt the same I'd keep it, the only way i'd get rid of it was if my performance dropped. It sucks in just about as much air from my cold air piping at the bottom as the stock airbox did, plus it's sucking air in uptop, so it's really a two'fer, and I've noticed more low end throttle response, mid range torque and a bit more high end WOT hp(that's cuz it's sucking air like crazy at WOT)
