K&N Cold Air Intake System: High-Flow Air Filter, Increase Performance & Acceleration: Compatible with 2011-2023 Chrysler/Dodge: 300, 300C, Challenger, Charger, 63-1114

For what it is, I'm completely satisfied. 1st off, it's not a "cold air" intake. Its actually sucking in hotter air than the stock air intake. However, it's sucking in 50 % more air than the stock air intake which in turn feeds more air into the intake. It does give you more low end power and much better throttle response. Not sure of how much more horsepower you gain because I didn't do a before and after dyno test. I did get better gas mileage though. I have a 2014 Charger Plus with the Road and Track package and I routinely make a 600 mile round trip back to my home town. Normally I'd average 23.4 miles per gallon on those trips. I made the same exact trip today and I average 25.4 miles per gallon. It's a great purchase for what it is in my humble opinion

When I got the box it was on I was stoked my check engine light came on so I unplugged the maf sensor let it sit for a bit drove around again shut it off sat bit longer and drove it and it was good to go . But that’s cuz I didn’t unplug the negative from battery . Altogether I was happy!!! The filter and setup instructions where was to do gonna need some tools .

Fitment is terrible. I had to make it fit in my 2015 challenger as it was not shaped correctly for it, the box was beat to hell and back. Overall, not worth the hassle of making it have to fit correctly.

Fits good. 2019 5.7 Challenger R/T Hemi.I don’t notice much performance or noise difference but it’s your average k&n filter so I didn’t really expect much.Looks cool though.Price is too much.

The ordering process was simple and the item arrived on time as promised. The instructions are somewhat vague as the pictures that are printed on the sheets are hard to see the details you need to make sure you are doing it right. I used the install video found Online. It was much easier to follow along and I was able to slow it down/stop the video as I did each step. The total time from start to finish was about 90 minutes. The exhaust has quite a noticeable and exhilarating tone to it after completed. This is with the stock exhaust. I almost don't think I want to do any changes to the exhaust for the moment as this upgrade makes it sound just right. There is definitely a noticeable change in HP. I don't have a dyno but I can certainly notice the difference. I am very satisfied with this K&N cold air intake and I recommend it highly to those starting to make modifications to their R/T.

The media could not be loaded. Works good differently a little more throttle response only problem was there was mo where to put the heat shield without the box hitting against some hoses to the radiator so I left that off and the bolt to brackets to stabilize it fell down the engine bay so I just left that off too but works fine without and is pretty stable too from just hanging from the throttle body but not worried about it

increased power and MPG - thanks

can’t tell a difference YET it’s way to hot where i live to even tell if my hemi still a hemi so when it’s winter i’ll come back and updateDef worth it , makes the car growl for sure !
