Q:Where are these plugs made?
Parttime
A:BEST ANSWERHi Bill, thanks for initiating contact. Autolite spark plugs were manufactured in various locations, primarily in Mexico and China. Historically, Autolite spark plugs were produced in the United States, specifically in Fostoria, Ohio. However, over the years, production has shifted, and many Autolite spark plugs, including some models, are now made in Mexico and China.
