Coolant hose clamp?

Looking to proactively replace some of these when I install my down pipe. Anyone have the recommended aftermarket clamp info and where to buy them?

McLaren used Oetiker clamps on the radiator hoses. The original clamps were not self-tensioning and over time the heat expansion stress applied to the hoses caused leaks. It is better to use self-tensioning clamps as the design allows for the different thermal expansion rates of the plastic radiator and also at the engine block metal connection maintaining a fixed compression force applied to the hose rather than exceeding the deformation limit of the hose.
I donít have size information.

My mechanic had me use Porsche clamps when they were leaking, working much better now.
