Youd think theyd be more popular, those overbraids for your hoses. I think the problem is that they are a b*****d to fit cos you have to disconnect every pipe, hose or loom that youre doing. Plus everyone knows that they are just an engine dress up part, not actually done for functional reasons, so its not so hardcore...
Im still trying to justify to myself having an alloy header tank instead of the sh*tty plastic one! Get a silicone hose set - a much better idea.
