Oil Cooler, Which hose size?

[Alex]

I got an oil cooler kit which has some -8 (1/2") hose and some 90deg 1/2" fittings.

I think the hose itself is an ok size but the internal diameter of the fittings is about 9mm (Getting the vernier on the pump hole on the block it's about 13mm) so I'm not sure if it's going to restrict flow?

I was thinking -10 but then the internal diameter of that hose is near 16mm so not sure if that's to big :P

Advice please.

not to big ,but no reason to change
1/2 hose has been std size for oil coolers since day one .
you are over thinking it
