Review on K&N Engine Air Filter 33-2460: High Performance, Premium, Washable Replacement Filter for 2011-2019 Chrysler/Dodge V6/V8 (Charger, Challenger, 300) by Cody Henry

So I bought this for my 2016 Challenger Scat Pack and added it to my Hellcat Airbox OEM system that I bought. Very easy to install. Because it is oil based, you will notice the intake air sound "FFFT" when you turn on the engine or drive. The noise goes away after a day but was very nice to hear while it lasted. With an OEM Hellcat airbox and headlamp tube attachment, you'll get 5-10 horsepower and a noticeable difference in throttle response. This gives you more boost at higher rpm, anywhere from 2.5K to 6K. Combining this with tune will give you more horsepower and will most likely see your horsepower in the 500s as I have said to other Challenger scat pack owners with the same setup. There is also a noticeable difference in the sound. The sound of the exhaust has become more aggressive and clear.
