Volant already has a CAI available for the 5.7L, which can be seen in several other threads on the forums.
I have been in contact with Volant a few times the past few months regarding the potential availability of a CAI for the 2011-13 Grand Cherokee 3.6L V6. The response I got today was:
"The cost of tooling is much more for a Volant system than it is of a kit with a heat shield so before we spend the money there needs to be a demand for the product currently there are only three inquires about a 3.6L. Currently we have not started tooling on the 3.6L. If the interest in a system builds we would start tooling sometime in August."
If you wish to review the Volant product line, here is the link:
So, if you are interested in a Volant CAI kit for the 3.6L similar to what is already available for the 5.7L, please drop a note stating your interest to Daniel Erickson at Volant and perhaps we can help get the product on the market:
