Re: Update on MOPAR CAI for V6 Pentastar

Have you noticed any increase in sound or power with the AFE CAI?

Re: Update on MOPAR CAI for V6 Pentastar

Am seeing quite high IAT on mine (over 120F on 80F day) but then the "hose" has gotten quite complicated over what Allpar showed for the 2011:


2011 Intake from pentastrs web site.

In counterpoint, my 2012 seems to have acquired several "chambers" right in hot air areas.


2012 Pentastar

Will begin by using a plain 3" tube from air cleaner to throttle body without the furnaces and will see if any difference. For stage 2 I may wrap the tube with exhaust tape.

My opinion is that 3" may be overkill for a 222 cid 6 but the TB is 74 mm ( 2.9") so will use that & monitor IMAP.

Do think the stock air cleaner and snorkle is adequate (same used for Hemi) so will see what just replacing the hose does.

Will mention that just replacing parts without recording IMAP and IAT values before and after will not tell you much.

I have noticed definite increase in sound......not sure on the power. It sounds like it would have more power but hard to tell if it really does or not. Waiting to see if it improves MPG.

Not really sure....I think it is a little better but that could be because it sounds so much better.

Re: Update on MOPAR CAI for V6 Pentastar

Just some quick noodling (and boring math in Excel) but if the IAT could be reduced by 60F (from 150F to 90F) then you would see about a 9% increase in compressed air density in the chamber and a concurrent increase in fuel trim (richer) to compensate.

More likely would be a 20F drop from 120 to 100 & a 3% change. That plus a 15F reduction in coolant temp might give a 5% increase in charge density. I would not expect any more.

Things to monitor before and after are IAT, coolant temp, IMAP, short and long term fuel trim, throttle position, and load values for steady state. Really would need a dyno for accuracy but all are available on the OBD-II feed (all that is needed is a notebook/netbook/laptop and a $30 thingie from Amazon).

The HEMI CAI thread has a lot of good info but for me, I want to know the IAT as close to the throttle body as possible.

Re: Update on MOPAR CAI for V6 Pentastar

I saw 180F IAT reading after a hot soak but came down to about 125F on the road.

Have got a pilot assembled but when spread to avoid the cam cover bulge, the top cover (with 3.6 VVT) does not fit. Stock "hose" has a major dent there to provide clearance. Not an issue since is just for testing.

Has anyone ever seen a smooth "hose" like the one in ithe Allpar 2009 photo ? Idf so does it have the furnace by the throttle body (cannot tell from photo).

Re: Update on MOPAR CAI for V6 Pentastar

The Mopar (AEM) CAI for the Pentastar passed California emissions in Dec 2011. I don't understand why it hasn't made it to market by now.

Re: Update on MOPAR CAI for V6 Pentastar

How would one check their IAT on the 2012 Grand Cherokee? Is it displayed in the EVIC?

Re: Update on MOPAR CAI for V6 Pentastar

You need an OBD-II reader. At the moment I am using a 7" tablet mounted under the a/c control but this picture gives you an idea what can be displayed.

My IAT normally runs between 20F and 40F above the ambient air temperature and the computer is all in by 100F so that is where I want to lock it on a 90+F day.
