NGK Spark Plug R0373A-9 Racing 3388

In order for the gasoline-air mixture in the engine to ignite perfectly, a stable spark is required at the right time. The right choice of spark plugs is therefore essential for optimal combustion and engine performance development. Particularly when it comes to the heat value, attention should be paid to the manufacturer's specifications. Be careful when using interference-free spark plug connectors, double is not always better, in this case no interference-free spark plug should be used, as the total suppression resistance would be too high. High-quality alumina silicate ceramic, creates a stronger insulator for optimal performance 98% pure copper core, provides excellent heat dissipation and conductivity Cold-rolled thread, prevents cross-screws and damage to the cylinder head Outstanding material coating, provides excellent corrosion protection NGK high-performance racing spark plugs are specially developed for racing and ideal for sports engines with constantly high speeds. In contrast to standard candles, they are particularly resistant to vibrations, heat loads and high speed. Perfect for trouble-free and performance-enhancing performance in demanding racing conditions. This type of spark plug is therefore not recommended for normal road traffic.
