In the clean air circuit from air filter box to the air duct going to the throttle body there is a short aluminium tube with one end cut and shaped to create a spin of the air flow. I dropped it while removing the air duct. I would like to know the proper position and orientation of the aluminium tube. I suspect that the blades shaped portion goes toward the throttle body and the rest of the tube to be Inside the air filter box. I Added a picture of the aluminium tube extending outside the air filter box. Can somemone confirm the position and orientation of this aluminium tube.
