What's firing your engine? NGK spark plugs are built to withstand the severe mechanical and thermal shock associated with high-revving, high-compression engines. NGK spark plugs feature electrode materials--precious metals like platinum or gold/palladium--for greater durability and low voltage requirements. Fine-wire center and ground electrodes provide better sparking and enhanced ignitability. And, the special arrangement of insulator noses improves throttle response!

So, what's firing your bike to the winner's circle? Whether you're a weekend warrior or an expert racer, rocket your way to victory with spark plugs from NGK--the people who spark winners!
