"Marbles in tin can" sound after installing K&N Intake

[LurkingLuke]

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?

Have you tried taking it off, see if the noise goes away?
