when the temperture is above 70 degrees there is a loud whinning sound from the air intake. it is not caused by the air filter, its extremely annoying. it does not occur in the colder temps only on warm days. my mechanic heard it and couldn't find it's source without a more extensive search. It" a 99 explorer xlt 6 cly engine. it doesn't happen all the time, but often enough . mostly when idling or at low speeds
