I'm looking at 3 different intakes for my new 14 3.6l limited.

Airaid is just the box and filter. Keeps oem tube. $176

K&N intake. $234

or a Afe Pr stage 2 for $297.

Just looking for a little sound, better throttle response and some mpgs.

Anyone have insight to what would be the better buy? Leaning towards airaid for price reasons but not sure if using the stock tube makes that much of a difference.

Thanks

Some people don't believe a cold air intake actually give improved power and throttle response. I can't agree or disagree with them until I see factual dyno testing and IAT testing. A open air filter that sucks hotter air AND raises IAT temps, does nothing but increases sound and some times reduce low end torque. A QUALITY cold air intake with a good heat shield/box, tube, and filter will help if the existing inlet system is a restriction. And someone needs to use a flow bench to check for pressure drops through the intake system to measure restriction accurately, which, on the 3.6 WK2, I doubt there is enough interest in the aftermarket companies to do those tests, R&D, and release it to the public.

Biggest thing a CAI does for mine is to cool down faster after hot soak. Tube is too long and coolant temp is too high to do much at cruise.

Also be hard to beat the stock air box since cool air is drawn from in front of the rad support and filter is the same as for a Hemi.

What we really need is a 180-185F fast opening thermostat

The reason why aftermarket CAIs make so much noise is that they replace the stock air tube which has a resonator(s) on it. I think if you do a search on YouTube Airaid has a video in which they specifically state it isn't much louder than stock for this exact reason.

I have a K&N on mine and it's a little louder than stock just riding around town and MUCH louder at WOT. I did not notice a mpg benefit, nor did throttle response change.

Here's an in-cabin video of my K&N:
