    I have an 88 528e that sometimes makes a noise while accelerating in 1st gear, it sounds like a big rush of air, almost a "whoosh" sound. Could it possibly be a leak in my intake system? Possibly the reason the noise is only there during 1st gear could be that my rpm's are rising faster then any other gear. Any ideas?

    Nope. This is normal; my 325e does the same thing.

    I didn't notice is either until I got a new muffler installed. Before mine was rusted through and had holes, and was loud enough to not hear much of the little noises, but once that sucker got replaced, I heard a whole new world of normal engine noises that I haven't heard in a long time, this whoosh being one of them!

    If you have a leak in your intake system big enough to hear, you won't be doing much in the way of accelerating ...

    It's not a leak. :)

    Also, it happens a little in 2nd gear.
    By the time you reach 3rd, the air is rushing by around the car fast enough that you can't hear it (if you have your windows down). You can't hear it even with them up though.



    I personally don't care about the sound. I think it makes it sound a little bit more... "mighty". :D
