About this part

Product Details

The fine wire center electrode on these NGK Racing spark plugs is a key design choice, ensuring both durability and a consistently stable spark, even under demanding conditions. These plugs are built for extreme use, ready to handle the rigors of racing and high-performance driving. The iridium alloy used in the center electrode has an extremely high melting point, making it well-suited for today's advanced, high-output engines.

Beyond the electrode material, NGK incorporates a pure alumina silicate ceramic insulator. This provides superior strength and helps with heat transfer, which is crucial for maintaining optimal plug temperature. You'll also find trivalent metal plating on the plug's exterior, offering excellent protection against corrosion and seizing, which makes installation and later removal much easier. The triple seals are there to prevent any leaks, ensuring the plug functions as intended.

This particular plug, the R2558E-10, is often used as a colder racing option for vehicles like the Scion FR-S, Subaru BRZ, and Toyota 86 from the mid-2010s. It's a well-built component designed to keep your engine running strong when it matters most.
