Why is an iridium spark plug better than a standard one?

Iridium is a much harder metal than platinum and has a higher melting point. This allows for a finer wire electrode, which requires less voltage to create a spark, leading to a more stable and consistent ignition.

Do I need to replace all my spark plugs at once?

Yes, it's highly recommended to replace all spark plugs at the same time. This ensures consistent performance across all cylinders and prevents potential issues that can arise from mixing old and new plugs.

What does the copper core in the spark plug do?

The copper core is a key component for heat management. It helps to draw heat away from the firing tip of the spark plug, preventing it from overheating and ensuring optimal performance.

Product Details

The fine wire center electrode on these NGK Laser Iridium spark plugs is made from an iridium alloy, which has an extremely high melting point. This design is crucial for today's high-tech engines, ensuring a consistently stable spark. These plugs are built to last, with an iridium-tipped center electrode that's six times harder than platinum, offering improved durability and performance over time.

NGK uses a pure alumina silicate ceramic insulator that provides superior strength and helps transfer heat away from the plug. For added protection against corrosion and seizing, they've applied a trivalent metal plating to the exterior. The copper core inside also aids in heat removal, preventing the spark plug from overheating. These are designed as an OE or equivalent replacement, meaning they meet the same high standards as the original equipment for reliable starts and consistent operation across a range of vehicles like the BMW K1200GT and K1300R.

When you're replacing spark plugs, it's always a good idea to replace them in sets. This box contains four plugs, which is perfect for many multi-cylinder engines. Make sure to check the fitment for your specific vehicle to ensure you get the right set.
