That is an idea I haven't looked Into! It is pretty quiet and I only heard it because after my intake install I was listening for every small noise imaginable 😂. After the car gets hot it is not there so It may be related to cold start processes which could explain it. I will likely take a look this weekend if there is anything loose but I appreciate it!
