I had the truck for about a year before installing the CAI and never heard this noise before. After posting this I saw a thread where it was explained as remaining air exhausting out the engine manifold when shutdown. The stock air box dampens this noise where as after market CAI’s don’t. I had a K&N intake on another truck and it didn’t make that noise so it caught me off guard.

Just installed an S&B CAI, and the truck response was what I expected. But right after the engine is turned off, there is a short pop or gasping noise. Its coming from the CAI area, and I can’t find another thread that mentions this type of noise. Is this normal, or anyone else having this issue?
