I installed my K&N CAI kit last night on my Stone White 2009 Challenger R/T. It was easy and took less than an hour. I like how it cleans up the engine compartment. I only drove it a mile or two to check for rattles before it started to rain so I didn't get a chance to see if I could feel or hear the difference.

 

Okay... That was in Feb. This is May.
How did it do?
Major difference in sound or performance?
What about fuel consumption?

Thanks!
