In this buying guide, I will share my knowledge and experience with these spark plugs to help you make an informed decision.

What are 6R12 Harley Davidson Spark Plugs?

Before we dive into the buying guide, let’s understand what exactly are 6R12 Harley Davidson spark plugs. These are high-performance spark plugs designed specifically for Harley Davidson motorcycles. They are part of the original equipment manufacturer (OEM) parts for most models of Harley Davidson bikes and are designed to provide excellent ignition performance.

Why choose 6R12 Harley Davidson Spark Plugs?

There are many reasons why I chose 6R12 Harley Davidson spark plugs over other options in the market. Firstly, they are specifically designed for my bike model, ensuring a perfect fit without any modifications needed. Secondly, these spark plugs have a platinum center electrode which provides better conductivity and lasts longer compared to traditional copper or nickel electrodes.

Another reason why I chose these spark plugs is that they have an advanced V-trimmed ground electrode design that delivers improved combustion efficiency and reduces fuel consumption. This not only improves performance but also saves me money in the long run.

How to Choose the Right 6R12 Harley Davidson Spark Plugs?

Next, consider the heat range of the spark plugs. The heat range determines how quickly or slowly heat is dissipated from the tip of the plug. It is essential to choose a heat range suitable for your riding conditions; too hot can cause pre-ignition or engine knock while too cold can result in fouling.

Lastly, ensure you buy from a reputable seller or authorized dealer to avoid purchasing counterfeit products that can damage your bike’s engine.

However, this may vary depending on your riding conditions and maintenance routine. If you notice any signs of wear such as misfiring or difficulty starting your bike, it may be time to replace them sooner.
