Choosing the right spark plug is important because it will improve the performance of your bike. These plugs help to prevent engine misfires and improve the efficiency of your engine. It is also important to choose a plug that is compatible with your engine. In some cases, the manufacturer recommends using one specific type of plug. In other cases, you can choose to install different types of plugs to get the performance. It is also important to choose the right size plug for your engine.
The number of threads on the spark plug determines how far the plug projects into the combustion chamber. A spark plug with more threads will be more powerful and reach the combustion chamber more quickly. This increases the amount of power and torque that the bike can produce. On the other hand, a spark plug with fewer threads will not get as hot. This allows the spark plug to burn the fuel more efficiently. Having the right spark plug size will help your bike to start easier and reach the RPMs needed to get to the engine's optimum speed.
Spark plugs made from nickel-plated, nickel-free, platinum, or titanium-platinum materials are used to increase the durability and performance of the spark plug. They also help to minimize tip erosion. However, they are more expensive than standard spark plugs. They may be suited for high-performance motorcycles. They are also used in off-road and all-terrain bikes. They are manufactured to withstand extreme heat and can deliver up to three horsepower.
The most common type of spark plug is a single electrode. The central electrode is made from platinum and the ground electrode is made from titanium-enhanced alloy. The platinum core provides superior spark performance and conductivity, while the titanium-enhanced alloy ground electrode improves the durability of the spark plug and extends its lifespan.
Another type of spark plug is the Autolite plug. These plugs provide better ignitability and reduce battery and starter wear. They also help to prevent fouling and increase the efficiency of the engine. These plugs also have a platinum sidewire to increase the power output.
NGK spark plugs are among the most reliable and powerful spark plugs. They are metal-plated and have a long insulator nose that helps to prevent pre-ignition. These plugs are also highly reactive and withstand extreme heat. They have a wide range of alternative options, including platinum and iridium spark plugs. The iridium tip of these plugs is laser-welded to provide consistent sparks.
Harley-Davidson spark plugs are easy to install and provide excellent performance. Their sintered alumina heavy-duty five-rib insulator dissipates heat well and is foul-resistant. These spark plugs also have electric seat heals to help prevent misfires.
Denso is a Japanese company that manufactures spark plugs for motorcycles and other automotive applications. They are also a leading supplier of automotive components for many automakers. They have been making spark plugs for vehicles for over 50 years. The company's products are OEM equipment for many automakers, including Harley-Davidson.
