Hey nice ride! Exacly like mine. he he
Your idea is good, hoever i do recomend very strongly that you atach the 2 little hoses to the new tube you are thinking of using. Just drill 2 holes in it the size of the tubing and then cylicone them so they are air tight because after all they are leading to the engine and if you get debris intheir it could mess it upin the long or maybe short run. What I did was just buy a cone filter from autozone, I pulled the air tube from the stock airbox and hooked it up to the new cone. This way your little hoses canstill suck in air from their factory box. Just tape off or cover somehow the hole left by the air tube (the top of the air box) soyou dont get debris in their either, i just used tape and covered mine. Now your wondering well ware the heck do I place the cone? well being that the factory hose is flexible I just tucked it under the long support bar and it is pointing to the left sitting on top of the fenderwell. Check out my website under What's new. You will see a very bad picture of what I mean. Oh yeah, and yes I did notice and improvement

To Jeep or not to Jeep, what's the question?

Or do what Atropine did and what I plan to do. Get a honda civic intake kit (because they are usually in stock at most parts stores) and use that. They are ALOT cheaper than Jeep ones and are basically the same thing with minor modification on the rubber connection to the TB.

Check out this guys mod on the intake. It's in his web page

Similar to mine except I left the factory air box on.

Go to a hardware store and try to find the right rubber connection. Probably in the plumbing area

I have one of a eclipse and you must connect both the rubber hosses. One is for the crank case to suck out pressure b/c its not a valve. The second is your evaporation canestor.
