How many miles till you should change them. I hear they can get weak over time and don't put out the spark they should.
I was thinking on swapping mine out of my 1995 Blazer with 135,000 miles on it.
I know it is never really mentioned as a maintanence item, but maybe this should be a good practise to get the maximum spark and economy out of our older vehicles?
