To ensure the engine's air-fuel mixture can ignite perfectly, a stable spark is required at the right time. The correct choice of spark plug is therefore essential for optimal combustion and engine power 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 can 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 required 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 Iridium spark plugs improve throttle response, proactively protect against carbon fouling, increase ignitability, and thus ensure smooth engine operation and prevent misfires and cut-outs. The very high melting point of Iridium is perfectly suited for today's engine technology and ensures excellent acceleration, fuel efficiency, and durability.

The fine Iridium tip ensures a consistently stable spark; additionally, the electrode coating provides excellent corrosion protection.
