The Ngk ATV PWC Marine SX4003 is a set of four spark plugs specifically designed for select Harley-Davidson models, including the FLHTCU, GLIDE ULTRA CLASSIC, and STANDARD JZ from the years 2009 to 2010. These high-performance spark plugs are engineered to deliver superior ignition performance, ensuring optimum engine operation and longevity.
The SX4003 spark plugs feature a platinum center electrode and a copper ground electrode, which result in a more reliable ignition and a longer spark plug lifespan compared to traditional copper-based spark plugs. The platinum center electrode provides a more stable and precise spark, while the copper ground electrode ensures excellent heat conductivity and resistance to corrosion.
These spark plugs are also designed with a narrow taper, which allows for a snug fit in the engine cylinder head and helps reduce the risk of engine misfires and backfiring. Additionally, the SX4003 spark plugs have a high-temperature resistant insulator, which allows the spark plug to withstand the heat generated by the engine without melting or failing prematurely.
The Ngk ATV PWC Marine SX4003 spark plugs are easy to install and come with a high-quality heat range that is suitable for most applications. They are also covered by Ngk's 1-year limited warranty, ensuring peace of mind for the customer. In summary, the SX4003 spark plugs are a great choice for Harley-Davidson owners looking for improved engine performance, reliability, and longevity.
