Q: US-made car parts vs. Chinese auto parts

Generally US auto parts are better. There are some parts in China that are well made. And there are some parts in China that are made like crap. The problem is you’ve got to know which are which. It’s very hard to tell sometimes, unless you are a mechanic like myself. There are some Chinese parts that I regularly buy and have no problems with. And then there are some that I stay far away from. For example, if I’m working on a BMW, and the MAF sensor goes, I have to bite the bullet and buy the OVM sensor that costs hundreds of dollars, because I’ve tried the 140-dollar Chinese ones and they all ended up with problems. They either didn’t work right in the first place or got broken after a few months. US-made parts are generally better in quality - but it depends on the part.
