A misfiring or hesitating engine, rough idle, and hard start are the typical telltale signs of defective or worn-out spark plugs. That’s because they have a big impact on combustion efficiency and engine performance, and you can only enjoy the power of your Harley’s V-Twin if these plugs produce a spark of the correct intensity and in the proper heat range while following the right timing interval. If that is not so, you are likely to end up with a rich or lean condition, which could result in your bike running poorly, guzzling gas, and your spark plugs having a much shorter service life.
Spark plugs use a metal electrode protected by a ceramic coating and are in charge of delivering the spark that ignites the air-fuel blend in the combustion chambers of cylinders, hence allowing the engine to work. Also, these devices function as heat exchangers, removing part of the heat generated during combustion through their ceramic part. Though modern plugs are durable and reliable, they need to be replaced on a regular basis, according to the manufacturer’s specs. In our online store, you can find a vast assortment of Harley Davidson motorcycle spark plugs and components from some of the most trustworthy brands.
