NGK Racing R5671A-10
It takes a high amount of precision to create spark plugs that perform their task well and are extremely resistant in doing so. NGK Racing Spark Plugs are designed for use in engines that have been fine-tuned to achieve maximum power.
What's firing your engine? NGK racing spark plugs are built to withstand the severe mechanical and thermal shock associated with high-revving, high-compression engines. NGK racing plugs feature special electrode materials—precious metals like platinum, iridium, and ruthenium—for greater durability and low voltage requirements. Fine-wire center and ground electrodes provide better sparking and enhanced ignitability. And, the unique arrangement of insulator noses improves throttle response! Whether you're a weekend warrior or an expert racer, rocket your way to victory with racing spark plugs from NGK—the people who spark winners!
