Any chance you can find out that part number? I ordered one and when I went to pick it up...it wasn't the correct one. Box actually said 1998 BMW E46. AND it was about 2 feet long by about 4" wide. Picture inside the box indicated that it was to fit just in front of the firewall instead of inside the cabin behind the HVAC stack. Supplier was Micron Air and it was $24.30. I'm sure a lot of us would benefit from knowing the exact part #. Hope you can help.....
