What brand of spark plug is made in the USA?
Several spark plug brands offer models manufactured in the United States, with ACDelco and Motorcraft among the most recognizable. Yet today’s global supply chains mean many plugs sold in the U.S. are produced overseas as well. Always verify the country of origin on the packaging or the manufacturer’s product page for the exact part you’re buying.

How to verify the country of origin
To determine where a spark plug is made before purchasing or installing, follow these steps.
- Check the packaging for a country-of-origin statement (for example, "Made in USA") and note the listed plant location if provided.
- Look up the specific part number on the manufacturer’s official site or the retailer’s product page to confirm origin details.
- Inspect the plug for any etched or molded country markings on the body or packaging, if present.
- Consult the product data sheet or warranty documentation, which may specify manufacturing locations for that part.
- When in doubt, contact the brand’s customer service or your automotive dealer to confirm whether a particular batch is produced in the USA.
Understanding origin matters for warranties, performance expectations, and personal preference about domestic manufacturing. Packaging and official sources remain the most reliable indicators.
Summary
In the current market, American-made spark plugs exist primarily under brands like ACDelco and Motorcraft, along with Champion for certain lines. However, production is global, and many plugs sold in the United States come from overseas facilities. Always verify the country of origin on packaging or through the manufacturer’s information before buying or installing a plug.
