Spark plugs can’t last forever, and here’s why: … Expanding, harder-to-jump gap: When a spark plug ignites, it has to travel across a gap of space in order provide the right level of combustion at the right moment. As spark plugs age, this gap widens as a result of extreme temperatures, debris and normal wear and tear.
