Better flowing intake for 5.7 w/Ecodiesel lower airbox

[Hemi395]

I just took a look at my 2014 (through the grill witha flashlight) and that area seems to be blocked by a cover of some sort. I'm not sure if it's part of the active grill shutters or something else. I'm planning on having the grill off in the next couple of weeks to do some headlight work so if this hasn't been definitively answered by then I'll post on what I find.

Awesome thanks! We've narrowed it down to either 2013 or 14 when they started cutting the hole there....

Strange..my 2015 doesn't have it either....

If it was a midyear change that might explain it. My 2014 was made in October of '14.

Still have to find a company that will ship it to The Netherlands...

I was looking at the pictures on AllMoparParts for both airboxes and noticed something. It looks like the Hemi airbox has a larger internal volume as there is a section that is not there on the EcoD part (see pic below). Not sure what the difference would do, if anything, but I thought I'd point it out.

Can someone who has ordered the EcoD part confirm if it actually is different? (i.e. The picture isn't outdated or otherwise inaccurate?)

The part # and pictures for the EcoD and the 6.4 are the same so yes, same thing.

Simple test to verify which has the greatest volume. Take both boxes, tape over or plug the holes, then fill each with water. Pour the water from each one into a container. Mark the water level for each one and you'll know for sure!

It's been proven by the OP with his air flow gizmo that the diesel one flows better, so why worry about it?

The volume is not saying everything, the flow is wat is important

My parts showed up the other day and I hope to get to it this weekend.

In the first pic Hemi395 posted that does not look to be the case. The EcoD box looks way bigger internally too.

I will take some pics if nobody beats me to it.

If you have a steady hand and a Dremel with a good assortment of bits, I think it'd do-able.

Well count me out..lol
