I added this to another tread, but am so pleased I thought I would add a new one here for everybody.

I found great windshield wipers (finally).

I had a variety of noises and bad wipers using new "inserts" from BMW for the originals. Even brand new I had issues. I recently replaced all three with new complete "Blades" and I am very happy with BOSCH MICRO EDGE from the regular old ordinary auto parts stores. There were only about $10. I also did so on a 3 Series Coupe and a third AWD Porsche that is my "ski" car and have been in serious Ski Season with lots or snow and lots or rain. And filthy "sanded" roads around Lake Tahoe NV / CA. I am very pleased!!!!

They installed right out of the boxes with no fussing, and no adapters or parts.. I just picked the "length" and bought them.

They do lack the "WIND SPOILERS" you may have but I have not noticed and issue, thought maybe that is ther for high speed. No problem at say 85MPH (i don't much go faster than that). The spoiler may be able to retrofit to the new one but I will probably not bother. Good Luck
