Running on K&N the past two days, 6.2L 2013, When the motor is cold, rolling on/off the throttle at low load/low RPN, I'm now getting a gentle-but-definitely-there noise. I want to keep anything else from breaking. Anyone know of this issue or where I should begin my research online or else poking around under the hood? Thanks in advance.

Make a video recording of the sound, post it to YouTube, and put the YouTube link in a new post here for us to review.

Not much experience with the newer than 08 stuff. But marbles in a can sound generally describes detonation. You positive all clamps are tight and you have no air leaks in the intake tube?
