Longer-lasting spark plugs

I have a feeling that spark plugs are made overseas. Whether they are or not, and whether delivery might be a problem or not, it's always good to save money. In the June Consumer Reports: although platinum-tipped spark plugs don't give your car more power, they DO last longer--"typically 100,000 miles between changes instead of about 30,000. But prices vary greatly. Shop around."

General Motors makes AC Spark Plugs in Flint Michigan. Since they are priced competitively, please buy them as any money spent on American production helps American workers.

Old Git,

Good tip! Quite a few of the newer model cars are now coming with the platinum spark plugs installed. This allows them to advertise 100,000 miles before a "tune-up" since the only thing left to tune-up now is the spark plugs in most other cars. However, there is one caveat. While the platinum tip may be good for 100,000 miles, the resistor in the plug body can fail at any time after about 50,000 miles. Thus, you may have one plug which will start causing a rough running engine. All things considered, this is still a better way to go than the old standard steel tip plugs.
