Red Line's V-twin primary case oil is designed specifically for 1984-to-present V-Twin American motorcycle engines, including aftermarket engines of similar designs. Similar to Red Line MTL, this product is for use in the primary chain case with wet-diaphragm spring clutches. Designed to operate over a wide temperature range, V-twin primary case oil improves clutch operation, while reducing wear and temperature. Where most synthetics are too slippery for clutch operation, this friction-balanced product is designed to provide less slip, smoother operation, and more power in modified engines.

NGK Iridium IX spark plugs feature an ultra-fine center electrode that's designed just thick enough to ensure the maximum durability and life of the spark plugs—and just thin enough to create an accurate and consistent spark. They represent the ultimate evolution of spark plug technology and performance. Iridium is the hardest metal used in spark plugs today—six times harder than platinum. This allowed NGK engineers to reduce the voltage requirement for a spark. Iridium IX plugs are available in more than a hundred configurations for universal and vehicle-specific applications.
