For the engine's air-fuel mixture to ignite perfectly, a stable spark is required at the right time. The correct choice of spark plugs is therefore essential for optimal combustion and engine performance development. Particular attention should be paid to the manufacturer's specification regarding the heat value. Since every manufacturer indicates the heat value differently, for example, a Bosch heat value of 3 may correspond to an NGK value of 9. For guidance, the manufacturer's specifications, including alternative spark plugs and their exact designations or type codes, are listed in every vehicle manual.

We work with official vehicle application lists from the manufacturers and offer you exactly the right spark plug for your vehicle.

Caution is advised when using suppressed spark plug connectors; double is not necessarily better. In this case, a suppressed spark plug should not be used, as the total suppression resistance would be too high.

• High-quality aluminum oxide silicate ceramic creates a stronger insulator for optimal performance
• 98% pure copper core provides excellent heat dissipation and conductivity
• Cold-rolled thread prevents cross-threading and damage to the cylinder head
• Outstanding material coating provides excellent corrosion protection

NGK Platinum spark plugs feature a single platinum tip, a core made of 98% pure copper, and a 0.6 mm thin center electrode, which optimize the spark and improve ignitability.

The trapezoidal ground electrode and the high-quality aluminum oxide silicate ceramic further improve acceleration, fuel efficiency, and durability compared to standard spark plugs.
