Originally used Glenlevit's  (forum member) genius Pizzabox Air Intake Field Fix mod then went permanent using Firewater Forged of Arizona's (forum member) basic design with a few twist of my own. The twist are: 1. At the air box junction behind the passenger seat panel I added a 2" ABS coupler to the end of the gray conduit and then shoved it into the factory boot and clamped it down. It fit super snug and seems to be leak proof. 2. I suck at bending 2" ABS so I went with store bought angles and cut my pipe to fit my standards and desired clearances. 3. I used a 2" flanged rubber spud washer in the 3" hole I bore through the wall of the bed behind and between the seats. Everything else I credit to W's simple, effective and well thought out design.
My tips are watch the Firewater Forge vid at half speed. Take pic's of the vid and reference them when you're cutting and building. Be patient. Do small increment cuts for exact fit. You can't add material if you cut too much off your pipe. His vid and my pics will tell you what you need to see to do this mod. I'll report back after I log a few hard days of running out in the MOJAVE DESERT this Fall and Winter rockhounding. I'll be doing the CVT intake mod W did to his Z8T this winter in my garage.
************ Intake mod finished / CVT Intake mod completed**************
Used the basic Firewater forge CVT intake mod design with one change. I used an off the shelf ABS 3" to 2" reducer as a bushing. It seems to be fine so far. I couldn't get the plumbing to fit behind the trim panels without it touching the exhaust pipe. I figured even wrapped in reflective tinfoil tape this was a recipe for disaster so I left it as is for now and plugged the drill hole in the bed. I'll make another run at it in the fall.
