I wasn't expecting much.
After days of reviews reading I chose it for my Challenger Scat pack.
Car runs with 485 hp.
If I gained some power I can't see it.
At the stops It rapididly increases the intake air temp but it dropped it even faster when I'm moving. When I drive constant With the front air duct opened and this intake I now reach a air temp 4°F higher than external temp. (It was 7°F with original)
I'm not sure how much performamce this can give you..
The sound is just a little deeper.

I had this professionally installed. I can not tell any difference in torque. It does sound like a very deep-throated lion's roar when I punch it, it's like riding the back of a T-Rex or something. I push my 2014 Charger R/T Hemi 5.7 pretty hard, hitting 100mph a few days a week, but I cannot tell any difference. The shipper was awesome, it arrived ASAP.

Have installed Airaid cold air intake system's on three cars and find the product very good although somewhat expensive considering it's simplicity. I will say, Airad is the least pricey of those offered yet equal in quality, fit, and ease of installation. This one, which was delivered with adapter's to fit multiple engines, aligned to every contour of the 392, Challenger Skat-Pack it was put on, looks like it was meant to be "standard equipment" and functions perfectly. I have always doubted the claim that any cold air package will add horsepower but do think the better "breathing" does increase efficiency of fuel/air delivery and may even increase gas mileage to at least a small degree. Just an observation - the official MOPAR version, being of a color different than the engine and components, would look out of place (obvious "add-on") versus this set-up PLUS, costs about 60% more!

Nice easy installation for my 2016 Dodge Charger RT. Took all of about 20 minutes and all the parts are easy to put together. You can definitely hear it from the driver's side with the window down when you accelerate at the end of the gear shift. I'm not sure if I noticed it improving gas mileage or performance but I wasn't really expecting it to. If it did, great. If not, I still have a cool little accessory in my engine bay and a neat sound to go with it.

For anyone installing on a 2016 Charger with the 5.7L, I would recommend you not installing this adapter from where the CAI meets your stock air intake hose to the other smaller hose coming out the side. They give you an extra 3 inch length of hose to attach and when I did, it made it too long and now that little hose has a pretty significant bend to it. (I'd try pulling it off but it's so jammed in there, I'll need a heat gun and pliers to remove it.)

Fit my 2015 Challenger SXT perfectly, sounds great.
