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 optimum combustion and engine performance development. Particular attention should be paid to the manufacturer's specifications when it comes to the heat value. Since each manufacturer reports the heat value differently, for example, a Bosch heat value of 3 may correspond to an NGK value of 9. For guidance, each vehicle manual contains the manufacturer's information with alternative spark plugs and their exact names or type codes.

We work with official vehicle usage lists from the manufacturers and offer you exactly the right spark plugs in a set for your vehicle.

Care should be taken when using undisturbed spark plug sockets, double is not always better, in this case no faulty spark plug should be used, as the overall interference 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 cylinder head damage
• Outstanding material coating, provides excellent corrosion protection

NGK Iridium spark plugs improve throttle response, prevent soiling, increase ignitability and thus ensure smooth engine operation and prevent misfiring and dropouts. Iridium's very high melting point is perfect for today's engine technology and provides excellent acceleration, fuel efficiency and durability.

The fine iridium tip ensures a consistently stable spark, and the electrode coating also provides excellent corrosion protection.
