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

I have installed one of these on an older 300 SRT 8 and loved the sound and boost in performance. I just put this one on my 2014 300 C and it was fast, easy and sounds great. Cold air really adds HP and the engine sounds much more aggressive. I always keep the old set-up and provide it when I sell or trade in the car. New owner might want to go back to stock.

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

It looks great under the hood of my 2021 Charger. It isn't a show car so I don't care as much for looks than functionality and it gets it done. I did notice slightly better performance from my Hemi.

I have the 63-1114 could air I take kits. First, I work on cars and very familiar with my way around a car’s mechanically but this filter is a nightmare. I tried installing on my 2015 Chrysler 300S 5.7L V8 and: 1. This does not install easy. STILL ISNT INSTALLED 2. The heat shield is not seating properly. It’s some a/c lines on the bottom of it and it following the contours of the engine body for a snug fit. 3. The twist bracket is hard to bolt to the location in the instructions. 4. The isstrunctions are WORTHLESS. 5. The YouTube video does NOT help. Way to fast and NOT detailed at all. 6. K&N Customer service said thid was the correct kit for my car. 7. Called K&N 3 Times for assistance yesterday (11/10/18), all they said was “You have the right part. Sorry I can’t help you”. That was 3 different agents. Im so disappointed because I bought and still have the K&N filter on another vehicle and I am very please with it and the installwas simple. See pics

Fit perfect on my 22 Dodge Charger RT. I would recommend the KN cold air intake to anyone looking to improve their vehicle's performance. It's a well-designed product that can provide noticeable gains in horsepower and fuel efficiency, and it's also relatively easy to install.

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 install wasn't to bad. Be warned, firing the bolt for the twist bracket behind HID headlights is not easy and you really have to work at it: once everything was in we drove and checked inside the engine. The filter didn't line up to well with the hole for the heat shield so we adjusted and now everything seems to run great. Haven't noticed an mpg boost due to the 32 degree weather but I noticeable sound and small throttle gain is precent. Without a tune it's hard to take advantage of these mods anyway. More testing needed but overall satisfied

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 .

I'll be honest, it wasn't what I was expecting, gas mileage got a lot worse, no extra power which wouldn't be noticeable anyways... car is a bit louder though but I'll be going back to stock most likely..
