Not at all.
First of all these things are not a cold air intake at all but rather a short ram intake. And it would not matter if the tube was 2 foot in diameter, the air flow to the combustion chamber would not increase. The naturally aspirated engine is governed by atmospheric pressure and no $200 tube with a filter on the end is going to increase flow or density. That can only be done by forced induction. That is a turbocharger or supercharger
In addition most of these tubes are made of metal, which would become heat saturated in about 20 minutes of driving. The ones made of poly are still mounted inside the engine bay sucking whatever temperature air is there, and I can guarantee its not cold.
Just sayin'

 

For those who don't know, the Android App Torque Pro allows you to monitor your Jeep's intake manifold temp. I wish that I had consistently done that before installing the snorkel because it would sure be nice to have some empirical data on the temperature differential between ambient (which you also can monitor with it) and intake. OEM. CAI. Snorkel.

Monitoring it, however, I can say that there is definitely a difference when driving slowly (overlanding), city and highway. The slower you go, the higher that engine inlet temperature climbs as heat soaking takes effect. You can be certain that it is heat soaking because you see it climb over the first few minutes of driving as the engine warms up. With a snorkel, the faster you go, the faster you draw air through the various tubing, air box, etc, then the lower that temperature gets. Not really sure you'd experience that drawing your air entirely from within the engine compartment, but that it just speculation. Let me also add that if you run high engine revs, the temperature climbs noticeable higher (such as forgetting to shift out of fifth gear on the Interstate, LOL), and that makes its way to the catalytic converters (which temp I also monitor). If my snorkel wasn't sealed to my air box, I'd pull it and see what happens, but that's a bit more hassle than I care to tackle.

 

Please explain how is the Volant intake air temperature lower than that of the stock intake, when both suck air at the same location ?

 

A solid 1/2 mpg gained in city driving with an AEV snorkel (to go with their heat reduction hood). Bought primarily for cooler air, because of Florida heat, especially in traffic. (Typically I wont drive in the summer afternoons). This is for a 2012 (3.6) 4 door, auto, soft top, half doors and KMs (not 2s) measuring 32" ht, max 45 mph stop n go traffic. Oh, and 3:21 (damn it. So much for special order). A Superchips Flashcal. And it just did turn over 6 K miles. 4 years owned this month.....for what its worth to the OP

 

I have a Bullydog tuner that can tell me the temp from the IAS and it was about 115 before the intake and about 100 after it in 95 degree weather. (I know I said lower than ambient in my last post, but I meant to say lower than before I installed the intake) It's most likely because the intake slot is larger and on the front of the intake, moving air through the filter faster, giving it less time to be heated by the rest of the engine bay.

 

Ok. I was slightly drunk when I wrote that, I work 12 hours a day on a horribly over-engineered aircraft, shoot me.

Lower temp air is more dense, which will create a little more power. Can you feel 8 hp in a 5000 pound Jeep with a high COG though, no. The intake manifold is still the choke point when you're trying to get more air through the engine faster to make more power with the same amount of fuel (this is called volumetric efficiency). If you were to port the head, you could get more of that denser air into the combustion chamber to make power that you might actually be able to feel. Sadly, our engines (3.6) have the exhaust ports/headers molded into the head, (thanks, Fiat), so there's really no way to speed up getting the spent gasses out of the cylinder, reducing the potential hp gain. This makes forced induction the only way to really add real world hp apart from regearing and making it feel like it's more powerful than it actually is.

 

The Pentastars were developed while Chrysler was part of Daimler, not Fiat.

 

The Chrysler Pentastar engines were introduced for model-year 2011 Chrysler, Dodge and Jeep vehicles. Fiat bought the Chrysler shares on July 21, 2011, so Fiat entered the picture too late to take part in the Pentastar design.

 

Yep. For the Wrangler, introduced for model year 2012.
