Developed by Earls at Silverstone, this is the solution to ensure improved oil feed to the crank on the R1M CP4 engine.
Using our in house machine shop we have engineered bespoke fittings, using the Earls Ultra-Flex hose created a light weight, flexible hose, this gives improved oil flow when required at peak RPM.
Included in the kit is the crank end bolt which has been modified for improved flow.
