Sweet, where did you get it and how much?

Re: Yup, Mopar 3.6 CAI is here ;)

That K&N certainly fooks nice but I am not a fan of their oiled filters, is that a dry element ? Is there clearance over the cam phazer and wiring ? What kind of IATs are you seeing ?

Don't take this the wrong way, but I'm pretty sure you are the only person on here interested in the IAT's...

Re: Yup, Mopar 3.6 CAI is here ;)

No he is not the only one. All these alleged CAIs, as far as I am concerned, only suck up hot engine bay air. In the Subaru world , with turbo engines so sensitive to heat soak, the vast majority either hang on to the stock air box or pursue a custom solution routing outside air from a fog light or fender. A cone filter in the engine bay is a no-no. any real or perceived gains are mainly due to the increased velocity pressure achieved by straight dicts and removal of those baffles/ chambers seen in OEM intake ducts.

Re: Yup, Mopar 3.6 CAI is here ;)

I would have to agree as well...what is the point of a "Cold air intake" if the temperature of the air is not any cooler? This is especially important to see if this upgrade is beneficial for performance, other than sound improvement, considering the stock air box is placed in a good position already partially separated from the engine bay

Re: Yup, Mopar 3.6 CAI is here ;)

The stock air cleaner appears sized for the V8 (used the same box/element) and draws air from over the raidiator support. The major issue is the sheer length and size of the stock tubing because the throttle body is at the right rear of the engine while the intake is at the left front so the tube passes in the airflow from the hot radiator. I have never seen a throttle body positioned like this before.

Also the thermal conductivity of PVC is about .25 and Aluminum 200 (W/mK) so a metal tube will transmit a lot more engine compartment heat to the incoming charge than ABS or CPVC. OTOH the convection Air to PVC or Air to AL is about the same. This means plastic will be slower to heat up but also slower to cool down.

Personally, am intereted in just one thing, keeping the intake charge as close to 100F as possible to maximise both charge density of the air and fuel atomization of 87 PON. Even on a hot Florida day.

Going cheap, I used a stock plastic intake hose as the basis but removed the connection to the furnace (rarely gets cold here) and the big box front and center.

Not seeing much difference after a hot soak but can really see the IAT drop on WOT however at cruise have to be travelling above 45 to get enough air flow to make a difference because the stock tube is just too big to get any flow velocity except at WOT.

To a certain extent this is why good turbos and superchargers have intercoolers to reduce the charge temperatures & maximise density. Is also why cars of the '70s gained intake hoses to an outside air source. (Stock cas, not just hot ones).

GM cars had a flapper designed to open below and close above an IAT of 100F. There was a reason.

^Agreed 100%.

As a past owner of everything from a Mustang mach 1...to a WRX, Evo, and STI...a CAI that draws air from the engine compartment is just a big waste of money, and cause more issues than they're worth (MAF scatter). Most of the time it's just a noise maker.

Why on God's green earth would someone want to spend about $400 on the Mopar CAI for their V6 which has fitment issues with the engine cover, and a metal intake tube which causes even MORE heat soak than the stock plastic tube?



I only spent about $50 for my drop-n aFe, and there's no way the Mopar CAI outflows it when it comes to my stock V6.

Did you notice any increased sound with the aFe? That's the only reason I have ever bought a CAI. The V6 is a little too quiet for me....sometimes think i'm driving a hybrid.

Do you know the reason for the huge expansion chamber in the intake tube? Is it sound reduction?

I'd like to try a straight plastic tube from intake to airbox and do the drop in aFe filter.

Re: Yup, Mopar 3.6 CAI is here ;)

Like this ? Just cobbled together, left the small resonator at the 90 degree to keep the engine cover mount.

BTW it looks like the K&N is in a box that is open to the duct over the radiator shroud. That does not use engine compartment air.

Very little...and that's OK with me.

It definitely looks like a sound resonator to me to reduce intake noise.
