i've installed my cold air intake and followed everything that the instructions said to do. But i am hearing this clicking/knocking sound come from the engine bay, from the inside of the car it sounds like knocking or popping but from the outside when i pop the hood it sounds like a clicking sound. It also sounds like it is coming from the left side of my engine area. The sound only happens when i light accelerate/decelerate. Any help would be GREATLY appreciated!
