Hey guys, my air intake on my 2002 325xi has started making a really bad whistling noise. I have been looking around to buy a cheap new one to replace the one I have now, but I only find air intake kits. I only need the air filter part of it. Anybody know where I can only get that part for under $50?
Here is the intake parts diagram:https://www.realoem.com/bmw/enUS/sho...diagId=13_0906,
But I suspect the whistling sound to be most likely caused by an intake leak at the rubber intake boot#3 or tube elbow#6,

If you remove and squeeze them, hard to find hidden cracks will easily appear.
