IMPROVED DESIGN: Our improved design provides a tighter fit inside the engine's spark plug hole to maintain the cap well in place through aggressive riding and to avoid debris accumulating near the spark plug.
INCREASED PERFORMANCE: Hotter spark for improved ignition at any RPM range.
DEALER'S CHOICE: No certified mechanics want to redo the same job twice. That is why our certified mechanics customers are unanimous, they are choosing our spark plug caps over OEM's one because they provide a safer, snugger fit for increased reliability over time.
