So I switched the factory intake with a cold air intake after that when the hood is open I hear a rattle sound coming from the engine or near it. Quick note: the engine to intake vacuum hose is extremely loose and fell of once during test drive after installing the cold air intake. I have also attached a video.

Thanks for the video, the noise does not sound bad like a bottom end noise, it sounds like something is loose. Can you tell if the noise is coming form the front of the engine like a timing chain issue? always check the engine oil as well. Plus does the noise go away once the engine RPM's have risen? Please let me know.

I think the noise is coming from the front of the engine like near the engine oil pulling thing not. The sound goes away when the cars rpm goes down and the vacuum hose been replaced.
