Four laser iridium NGK CR9EiA-9 spark plugs (stock code: 6289). 4 litres of semi-synthetic 10w40 Silkolene Comp 4 engine oil. Silkolene Comp 4 ester based premium semi-synthetic oil conforms to the following technical specifications JASO MA2 and API SL. Formulated to meet the needs of both air and water-cooled 4-stroke engines, Comp 4 10W-40 XP is the recommended SAE grade for many motorcycle manufacturers. The birth in 1908 of the innovative company that was later to become known as “Silkolene” was the vision of the entrepreneurial Dalton family of Belper, Derbyshire, England. Silkolene’s “lube cube” packaging helps reduce plastic waste and pollution. This “bag in box” concept offers a smart, highly eco-friendly alternative to rigid plastic bottles and is easier to store and use. Each Lube Cube is constructed from a durable 100% recyclable outer. Inside is a 98% recyclable plastic inner bag, which after use can be flattened and disposed of in normal licensed recycling waste. Any questions, please feel free to contact me.
