This well tested sump kit increases engine oil capacity by 1.3 litres! The primary advantage of running with a greater sump capacity is that engine temperature will be greatly reduced as the same oil is notbeing circulated so frequently. Secondly it will stay cleaner longer than a smaller volume of oil as any contaminants will be more diluted. Great addition to any performance upgrade! (COMPLETE WITH 2 SUMP GASKETS, PICK UP EXTENDER AND GASKETS & NEW LONGER SUMP BOLT SET)
