Q: In a recent column you responded to R.W. from Minnetonka, Minn., that he should not need spark plug replacement of the platinum tipped plugs until the manufacturer recommended 60,000 miles. One thing that is often not considered is that over time, the dissimilar metals in the aluminum heads and the spark plug materials make removal of the plugs difficult and potentially costly. Manufacturers tell vehicle owners that items have a longer service life than they actually do.
