How Do I Choose The Best Spark Plug for KTM?
Finding the best spark plug for KTM is like finding a life partner. With the right one, everything feels right. The right spark plug keeps your engine in shape, does not harm your vehicle’s other functions, and provides you with the expected services like acceleration, smooth engine idling, durability, and most importantly superpower because KTM bikes are made for racing and extreme conditions.
Before purchasing any spark plugs you should check on these factors:
- Fit Type: Make sure that the plug you are buying is the optimum fit for your engine’s spark plug gap. Most of the spark plugs these days come pre-gapped, if not, you can adjust them by yourself or seek the help of professionals.
- Spark Plug Materials: We are pretty sure that you have an idea about the metal used in a plug’s tip. There are three types of metal used in spark plugs such as- copper, platinum, and iridium.
a) Copper is the most conductive, but owing to its shorter life expectancy, it is not ideal for engines that operate in extreme circumstances, such as the KTM.
b) Platinum is more durable than copper, although it is less conductive than copper and iridium.
c) iridium is the most powerful and long-lasting metal of the two. Because this metal can withstand harsh temperatures and conditions, iridium plugs are commonly used in KTM.
Besides, as technology advances, manufacturers are improving the materials used in spark plugs. Recently, metals such as gold, silver, and palladium have been used in the tip of a spark plug for enhanced and updated performance.
- Budget: This is one of the factors that we take into account seriously. Before purchasing, read the manufacturer’s catalog. Many think expensive plugs are good plugs. This is not the case. The price of the spark plugs is modest in comparison to other automotive parts and the price range varies between brands, materials, and technologies.
- Stroke numbers: KTM motorbikes have two types of engines – 2-stroke and 4-stroke. In a four-stroke engine, you need two pairs of distinctive type spark plugs. Make sure which type of engine you have before buying any plugs.
What Size Is a KTM Spark Plug?
The KTM spark plug socket measures 14mm in size. Some spark plugs have 16mm sockets, but late-model KTMs require a 14mm spark plug socket. Always use locking extensions when installing spark plugs to prevent the socket from becoming stuck to the spark plugs. Use sockets with a magnet or a rubber sleeve inside for this.
