I did research too on every part manufacturer, and in my opinion everything made in china this days even Federal Mogul (Moog), All so called "Germam" companies including Bosch made in china too. I guess Motorcraft is just re-badged parts not real manufacturer so fall in same category.
There real question nowadays days if they have factory in China that produces quality parts using strong steel. I bet big companies do.
There's some mid-range part manufacturers in Italy and few other countries, but they far not as good as Chinese quality parts from Bosch for example.
In Los Angeles AutoZone only has Duralast (Chinese Autozone Brand) and Valuecraft pumps for Taurus, no Specrtra pumps.
Here the marketing catch, "<company name> Germany" does not mean they make products in Germany its just means company is registered in Germany, but factory can be in Taiwan.
Same for Spectra i am afraid look at their website http://www.spectrapremium.com
on homepage there's slider where its saying
Engineered and designed in North America, word Engineered could have many meanings, they would say Made in USA if they had nothing to hide.
If you want to check just shoot email to any manufacturer you like and ask if they make parts here or import from China, its not a secret they will tell you.
