K&NCold Air Intake System: High-Flow Air Filter, Increase Performance & Acceleration: Compatible with 2011-2023 CHRYSLER/DODGE, 300, 300C, Challenger, Charger, 63-1564

Excellent addition to my sons 2021 Challenger. Added a little horsepower and from our records, has added an additional 3 mpg. on the highway, the city miles have been the same to this point. Also added a deeper sound to the car. You definitely notice a little more pickup during acceleration. You can never go wrong with K&N and this time was no different. K&N cold air intakes are on all of my cars.

Awesome add on! I finally pulled the trigger and purchased this great cold air intake for my 2012 Dodge Challenger SXT Plus. It took me about thirty minutes to install. Probably because I downloaded the instructions while waiting on my two day shipping. (Don't hate, I was excited) Very easy install, all parts were correct and the instructions could be better thought out but you get the idea.Starting my car for the first time after install, I noticed a little bit of a deeper rumble from the exhaust. Not a huge change, but a change indeed. I drove down the street and started to hear the shallow whine a lot of people say they hear when shifting gears. After a day or two, it went away. (Or I tune it out) I continued on and punched the gas. A much deeper exhaust roar came out! Mostly between 4,000 and 6,000 rpms. Also, a deep roar from the engine. This intake really makes it sound more like a V8. Key word MORE. Still a big difference between the two. There is a definite pep in the acceleration too. I've taken about a full second off my 0-60 time.In the five days since the install, I have noticed better gas mileage on the highway. Now I'm seeing 28-31mpg. I was at 25-28 mpg. I drive a lot. I probably shouldn't have a challenger with the miles I put on it, but I love this car. Spend the money and buy this intake. You will not regret it.

The best. Car sound on charger 100% went from kitten to teenage tiger. But do it for the function and not sound. It'll take just about 1.5 to 2 hours. Make sure to pre-screw all the smaller screws to save some time. Do it on a table or floor. No dropped screws in the vehicle under the hood. The air intake feels a lot better when driving. Also quiet as a church mouse when regular driving. Will only get loud when you step on it. Have fun with this. Your car will thank you and looks cool too.

First things first a quick description. I have a 2012 Challenger SXT Plus with the SS package. I have removed the engine cover and as much of the foam around the engine as possible. I prefer the look and sound of the naked engine. So the car was already a little louder than stock.Having said that, the new CAI definitely makes the car louder, especially when you hit the gas. I noticed better throttle response in the lower ranges in both normal and sport mode. It really comes alive past 3000rpm though. I made a few quick passes with the throttle wide open and although the intake whine was audible, it was quickly overcome by the sound of the engine and exhaust. As good as the stock air box is (same as the R/T and SRT8), this CAI is an improvement. I also noticed a slight increase in MPG. There was some initial fluctuation in the average MPG as the ECU was trying to compensate, but after a few minutes it seemed to iron itself out. Also the intake tube is plastic, I was not aware of this prior to ordering. It is a very thick and sturdy plastic so I am not worried at all. I was just under the impression it was powder coated steel. on the bright side, this should make it easier to paint.Installation was basically easy once I understood which parts were being discussed in the description. Here is a few tips that I learned from the installation:- The air flow sensor is very fragile and tricky to remove. Take a close look at it while it is in the stock tube. There is a piece of plastic that sticks out to the side on the sensor. Gently but firmly give it a quarter turn counter clockwise. It should pull freely after that.- The cable that attaches to the air flow sensor is already a little taught in the stock configuration. The new placement is a little farther away and you will need to find some slack. I had to "mold" (read bend the crap out of) the plastic clip that is holding the wires in place to get it to fit.- Put the basic pieces together and do not tighten any of the hardware until an approximate fit is made. I found that the intake tube did not fully line up with the throttle body at first and needed a little finesse to get it in place. I found it was easier to have the rubber sleeve attached to the intake tube first instead of the throttle body.- Also measure the crankcase breather tube and cut it to fit. They supply a tube that is too long.- The kit I purchased came with a dry filter (I am assuming since it didnt come with any oil). I dont remember seeing any description.- Also the bolts are not uniform so be prepared to use multiple sockets.That is all I have at the moment. I am glad I went with this one over the polished intake. It just seems to fit the look of the engine compartment better in my opinion. The added 1 HP was also a bonus.
