With age, the two long pipes that supply oil to the oil cooler rust and eventually crack and fail, which can be catastrophic. Our replacements are made from mandrel bent aluminium, with the flexible parts Kevlar reinforced. The mandrel pipes also one piece, whereas the Nissan pipes have a join and potential leak point, just behind the cooler. They are a direct replacement for the Nissan parts and bolt up to all existing brackets and fixings. The whole assembly weighs just one third of the OEM Nissan lines, and is less than one third of the price!
