Spark Plug NGK SILZKAR7B11 (93482)

The NGK 93482 (SILZKAR7B11) Iridium-Platinum spark plug is an original equipment (OEM) component for many modern Japanese vehicles, specifically for Nissan, Infiniti, and Subaru brands. The use of precious iridium allows the center electrode diameter to be minimized, guaranteeing instant ignition and stable engine performance across all operating modes. A platinum chip on the ground electrode prevents wear, keeping the 1.1 mm gap consistent throughout the entire service interval. The Long Reach thread design improves heat exchange with the cylinder head, protecting the engine from overheating during prolonged loads. This plug is specifically adapted for the latest generation of electronic engine management systems, ensuring complete fuel combustion and minimizing misfires. This guarantees not only smooth engine operation but also protection for the expensive catalytic converter.
