Can Spark Plugs Last 100,000 Miles?

There have been times when the technicians at 12th Street Auto Care Center have found spark plugs seized in the cylinder heads of some of our Sioux Falls area customers' vehicles with as little as 60,000 miles on them. The removal of these seized plugs can result in hours of labor by our technicians at 12th Street Auto Care Center. There have been rare occasions when 12th Street Auto Care Center has needed to remove cylinder heads just to get the spark plugs removed. 12th Street Auto Care Center suggests that in order for our customers in the Sioux Falls are to maintain peak performance for their vehicles, that their spark plugs should not be run longer than 30,000 miles. 12th Street Auto Care Center suggest that consumers should take those 100,000 mile spark plug marketing claims of manufacturers with a grain of salt.
