Are the Stock porsche clams plated with Zinc .. Some of the hoses seem to have a
golden look to them while others don't
I have a place that carriies the stock brand Norma
Are the stock ones the best to go with ?
I am thinking of using the constant torque clamps on the leakers
you know the one on the water neck and the metal tube that are
notorius for leaking
Does anyone have a list of the hose clamp sizes needed ?
Thanks in advance
regards
Ed
