I am sure it was a Chinese copy but the finish, fit and operation was just as good as the OEM... And don't think for one minute that BMW builds the MAF, because I am sure they sub it out to other companies who may build the OEM in China... I also buy Harbor Freight tools, which I find to be a fantastic value over the name brands. Its not the American worker can't compete with Chinese workers,, its all the restrictions imposed on our industry by EPA, Federal, State and local government. I can order a typical HDMI cable from China for $3 including shipping or go to Best Buy for $19 plus tax. Heck, we can't even ship the cable to the next town for $3....
