spark plug

Have you always wondered what a spark plug does? Our team here at The Wrench is here to help you out. It's simple in theory but does quite a lot of work for such a small piece of equipment. Your spark plug forces electricity to arc across a gap like a bolt of lightning at high voltage and fits into your engine's cylinder head, where it “sparks” to ignite the fuel and creates combustion within your engine. Without it, you wouldn't be able to drive your car or truck.
