I had information from a vendor that G3 Volant would have aluminum lid:
"I wouldn't want to steer you wrong on the answer about the aluminum lid, but back in November Volant told us they were moving to the alum lids and at that time it had nothing to do with the fit of the lid. Volant had problems with their initial design because it didn't mount right. Then people complained the lid didn't fit tight and the next thing I knew everyone had started saying that was the reason of the new aluminum lid. Volant told me this week another 2 months for the alum lid, which leads me to believe there is not an issue with the current design - but that is more my opinion than direct knowledge. I have never had a customer complain about the gen2 design, although I know of people who improve on the gasket between the lid and box, but that is for several models, not just Nissan. I agree Borla is the best bet for exhaust. Corsa makes a great system as well but has yet to deliver for your vehicle."
In another email he provided:
"Same intake for both Titan and Armada. When you make the install the only thing to watch out for is the original position of the MAF (shiny side up I believe). If you don't get it back correctly you will have check engine light issues. Volant has one of the best tech guys that will walk you through the install if you have any questions -

Not sure whose source is correct, maybe someone in CA.com has a connection at Volant or wants to send a query to "daniel".
Anyhow, that's all I can contribute.
