So my plan is to save some money and try to dump the intake muffler right before the T/B and use the stock airbox. I can make it myself using silicon adaptors and piping, but I just noticed this unit that's made for the Challenger R/T which uses the 5.7L engine of course.

Looking at it, I'd say it's too short to work, but I'm also unsure what the diameter of the ends are. I was just wondering if anyone has ventured down this path. This fits all of the Hemi Car engines 05-15 5.7-6.1.

This would be a winner if it fit, but I'm seldom that lucky! :(

Here's the link to the item: Mopar Non-Silencer Intake Tube 05-15 Challenger, Charger, 300, Magnum 5.7L, 6.1L

It looks too short as our air box bends back a bit but who knows. Since it's an OEM part maybe find a dealer that would let you return it?

Sorta makes you wonder why Dodge went to the trouble to design the intake box for the Durango. I also wonder what the set up looked like in the Pick up's before the intake change.

I'll confirm in the morning, but doing a quick measurement looks like the D intake is almost 5" longer than the 300.
So it might work if the 300 tube will stretch and it looks like it might.

Seriously appreciate you testing this!

The answer is...NO.

Its too short and won't stretch the distance..needs about 4".
There also is another issue regarding a temp sensor that is located in a different spot on my 300 Hemi than the D Hemi which would require relocating the sensor and plugging the other hole.

Thanks Chase! I saw the IAT sensor and that's a fairly easy fix, but I broke my plastic stretcher so I'll have to build my own tube! Thanks a ton for doing all this work!

No problem, both easy to take off and swap.
One solution would be to cut the Challenger tube somewhere in the middle and put a 4" extension using metal tubing of the same diameter.
It fits on the TB and the Airbox, so just needs to be lengthened.

You could cut the expansion part off the Durango's intake, and use that to bridge the gap between the challenger/300 tube and the Durango's air box?

It appears if it was cut where the expandable tube meets the solid plastic, the Challenger tube might fit over the end.
