Gears and Gasoline: Modifying Your Car With Spark Plugs

Carolyn works on the content team at Advance and enjoys writing the occasional story. She grew up watching and learning from her father who enjoyed working on cars. He often purchased vehicles in the $200-400 range and completely restored them, even the paint! Her first vehicle had 230,000 miles on it. In her free time she loves to travel, ride horses, be outdoors hiking, biking or exploring with her family.
