The great oil filter debate

They have been wholly owned by Mann + Hummel of Germany for around 10 years. Wix was also bought by M+H a couple of years later.
They'll still make filters in NA for now, but the trend continues to be globalization of companies.
Just because it's not made in U.S. doesn't mean it can't be good quality. It all depends on the design criteria, manufacturing capacity,, quality control, and management. That being said, because I was a union machinist for almost 20yrs, I PREFER "Made in USA". That's why I only buy 'Murican cars, and I DO NOT repair foreign vehicles. You buy a foreign vehicle, you're on your own in my book.
