Review on 🏎️ K&N Cold Air Intake Kit: Boost Horsepower with The Ultimate Performance Upgrade - 50-State Legal for 2005-2015 Dodge/Chrysler V8 Models (Challenger, Charger, Magnum, 300C), Part #57-1542 by Michael Hall

Now I want to start it took me and my brother about 2 hours although it says about an hour because it's "one size fits all". and does not quite 100% match my 2013 RT AWD charger. The biggest problem was the heat shield, it didn't go down far enough so the cone filter didn't fit 100% in the end so we had to rearrange something and push in until it went in. But it worked and the ID says I got at least 1mpg. I haven't actually studied it too much, but I think I'm 16-18 now instead of 15-17. It's okay, but it's there. Also, the car sounds a little better under the gas, but not like "wow, that thing is loud”, but better. It has decently more power, but not a huge change in throttle response or anything like that.
