The average motorist often underestimates the power and importance of a spark plug. Spark plugs must deliver a high voltage spark within milli-seconds in order to ignite the air and fuel mixture inside a vehicle's engine.

This process provides the power a vehicle needs to operate. Old or worn spark plugs can disrupt this process and diminish the amount of power that is generated. According to AA, old or dirty spark plugs can reduce fuel economy by up to 30 percent.

To keep bikes running their best, you should replace spark plugs according to the intervals outlined in their vehicle's owner manual. This will not only help riders see a difference in vehicle performance, but also could save them money at the gas pump.

Always make sure that you are buying the best spark plug (and the correct size) for your particular bike. Use what the manufacturer suggests, or feel free to get advice from knowledgable motorcycle mechanics. This does not mean the kid at the local parts house!

If you know any racers, get their opinion on plugs that can help your motorcycles performance. And yes, there are differences between the spark plugs for a car and ones for a bike!
