I have a 2014 Challenger R/T and I am looking at options for a CAI. I found this K&N and like the oil-free feature. (http://www.autoanything.com/air-intakes/kn-71-series-blackhawk-air-intake-system) it says it is "custom fit" for my year model of car. In searching I found it says on some sites it is made for the 6.4l engine and doesn't mention my 5.7l. Will I be able to use this intake with my car? If not, I am looking for an oil-free solution and would like to find one that replaces the air duct so I wont have the resonator anymore. Thanks in advance for the help, I am new to this stuff.
