Can Spark Plugs Last 100,000 Miles?

There have been times when the technicians at Pro Power Transmissions have found spark plugs seized in the cylinder heads of some of our Brooksville 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 Pro Power Transmissions. There have been rare occasions when Pro Power Transmissions has needed to remove cylinder heads just to get the spark plugs removed. Pro Power Transmissions suggests that in order for our customers in the Brooksville are to maintain peak performance for their vehicles, that their spark plugs should not be run longer than 30,000 miles. Pro Power Transmissions suggest that consumers should take those 100,000 mile spark plug marketing claims of manufacturers with a grain of salt.
