    Denso Spark Plug, Copper

    Spark plugs are not all alike. With the world-famous DENSO U-Groove spark plug it's easy to see, thanks to its patented U-shaped ground electrode. The U-Groove forms a channel for the spark nucleus to form at the instant of ignition, limiting quenching to generate a more potent spark. The premium features don't stop there: DENSO's distinctive five-rib insulator in purified alumina prevents leakage and flashover, while dual internal copper-glass seals and a copper-core center electrode with nickel-alloy tip assure reliable spark delivery. To keep your engine running smoothly, its spark plugs must fire 25 times a second or more. If just one spark plug skips a beat you'll know it instantly, with rough running, poor acceleration, and reduced fuel economy. DENSO U-groove spark plugs combine dependable performance and superior value.

    Important Information: If your bike is a single spark model then you will only need one spark plug. The twin spark models (2004 and up) require one main and one auxiliary plug witch are the same. so you will need two.
