Obligatory reference to this thread's predecessor: Evolution of a CAI
---------------------------------------------------------------------------------------

Here was the last of my tries that used the 3.5L OE air intake tube (for its IAT mount), part of the 3.6L's OE air intake tube (for its non-metal-ness), and part of an aftermarket CAI's setup to get the filter element down below the fender hole and into the cooler air: https://onedrive.live.com/?cid=1e7a...127163&ithint=album,&authkey=!AHV3KAxv1ciZMA8

That design was good on paper but turned out to have some real-world issues that I needed to address with my next iteration...

--------------------------------

Here is the next attempt to fix what was wrong with the last one: https://onedrive.live.com/?authkey=...=1E7AD039B9F2BE81!127161&cid=1E7AD039B9F2BE81

That design was almost what I wanted/needed, and it is actually very close to what I have today, but that was a pre-Prius version of what I have now, so not exactly the same as now.

--------------------------------

Here is the final version (so far) that totally gets rid of the 3.5L parts and goes with the 3.6L OE parts (yes, duct taped together where necessary) and currently utilizing a very ugly (but highly functional) holding bracket:
https://onedrive.live.com/?authkey=...=1E7AD039B9F2BE81!127162&cid=1E7AD039B9F2BE81

This design is the most satisfactory so far. It is still prone to heat-soak from the contact and near-contact with the engine coolant overflow tank, but that's pretty much unavoidable with the 3.5L's plenum design. However, the utilization of the 3.6L's air intake tube parts (plastic as opposed to rubber) mean any absorbed heat-soak is bled off significantly faster after raising RPMs (by opening throttle and bringing in moving air) than previous designs.

I watched the IAT sensor reading go from almost 150F sitting at a red light down to 92F (same temp as air surrounding filter element) in just one WOT run. That is MUCH better than the 3.5L's OE designed air intake setup can do. It would take several WOT runs to get the IAT temp down to somewhere close to being what it should be.

--------------------------------

And that's ultimately the main goal I have been after this whole time - I don't care about pulling in the coolest air possible. What I want is to make sure the air that is being pulled in has its temperature measured and reported accurately by the IAT sensor.

That's a much better goal to go after IMO!! (not to mention it is a goal which yields more ROI for the torque-challenged Challengers like mine).
