The loud noise comes from the wheels of my Mazda CX 9

If it is one of your tired bearings, it will tend to make a thumping noise that intensifies when it is under stress (spins faster and faster). So keep in mind to examine by driving “fast” (neutral gear on and window open to hear only the noise of the wheels) that the noise is located here, if this is the case replace it or them quickly. If it is a deformed tire, remember to visually check the entire tread area for linearity. If it is the balancing of the wheels of your Mazda CX 9 that is the trouble, you will tend to feel a vibration in the direction of the vehicle as you go faster.

If the loud noise on your Mazda CX 9 is related to air intake, the control will be done mainly visually, check all your air intake hoses by a visual control in your engine block to be sure that it is not damaged or disconnected which would induce an air intake, if it is just disconnected you can reconnect the air intake tubes yourself. Then examine that the engine idle speed is not random. In case you confirm one of these two disorders, take your vehicle to your garage .
