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

Improved my MPG by 10-20% depending on how much I stay out of the loud pedal (20 MPG improved to 22-24 MPG), and if you do choose to push the loud pedal you are rewarded with a nice, loud noise, especially above 4,000 RPM on a Dodge Charger with the 3.6L Pentastar. Normal driving nets you no additional noise, which is great for cruising since there is no drone. Throttle response is ever so slightly improved and the engine runs more smoothly. Why Dodge doesn't do something like this from the factory is a mystery to me. Why wouldn't you want increased MPG, smoother revving, better throttle response, and a louder noise from your 300 HP muscle car?Instructions weren't super clear and fitment was a bit tight in places, but it does go on without too much effort. Two heads are better than one in this regard; have a buddy help you. Mine had the appropriate hole drilled for the air sensor unlike some others. Go ahead and cut the zip tie that holds that bunch of wires together to make it easier to insert the sensor into the tube, and then retie the wires after you've got it fitted.

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.

Bought this for my Dodge Challenger SXT Plus. I was able to install it myself. I noticed about a .2 increase in miles per gallon as well as a little bit more responsive driving experience.The sound difference was small, maybe about 1DB louder, but you do get that nice little whistle when you're accelerating sometimes (although I thought I wouldn't, I actually like that sound now).It also makes the engine bay look better in my opinion.With the slight increases in MPG, performance, and change in the sound, it was worth it for me.

I've owned K&N Cold Air Intakes for my past several vehicles. My primary reason for installing this kit is to give a better, smoother throttle response with less lag. To me, it doesn't necessarily add power, but it helps deliver power more evenly when you give it gas. The Intake also removes some of the stock sound suppression, so it makes the engine sound a bit more sporty when you stop on it. I suspect it's heard more in the cabin that outside, but it's a nice throaty sound.I've heard folks suggest that this may save you MPG. My personal experience is that I tend to be a little more heavy on the gas pedal, while enjoying the more throaty sound, so if there is any fuel mileage improvement, I'm probably negating it by applying the throttle more aggressively.Installation is easy and can be done by most everyone with tools. Be sure to save your original intake in case you need to replace it when you trade in. Most dealerships do not appreciate the upgraded intake. I've installed this kit on 2 Jeep Grand Cherokees, Chrysler 300, and Ford Pickup.If you are expecting to turn your vehicle into a dragster, an intake alone won't cut it. But if you want a more responsive throttle, a custom look, and a more aggressive sound, this will do the trick at a reasonable price, without major modifications.
