Its COOOOOLD out. I have recieved a few phone calls about strange vehicle noises the past few days. Remember, cold air is dense, dense air will create strange and annoying howling and whistling noises in some vehicles air intakes. It will not harm your car or truck. manufactures design intakes with a degree of noise suppression from the factory, to aid in noise reduction at most ambient temps. dense below zero temps are not incorporated into the design. if your car or truck makes a strange noise in the cold, an easy way to self diagnose if its just cold air or something else is to pull it in a warm building such as a car wash n see if it stops.....thanks for reading.
