Yes it is a K&N CAI. I don't know the model, I went to 4 Wheel Parts and asked for a CAI of the K&N brand and that's what they gave me. I def can hear the difference of having a CAI vs not having a CAI. Can I feel it? I don't know, The truck already has so much power what's 10 more HP? Plus I have a Flowmaster exhaust system that together they sound mean and thunderous and will throw you back into the seat when you stomp on the gas.
