oil coolers - cheap vs. expensive

[Bazda]

I have 2x setrab coolers on mine lol.
A 16 row one wasnt enough, so added a long one inside the grill.

Good oil coolers but yes quite $.

The latest NZKW fittings seem to be ok. I run the olive style ones on the fuel side and they look of good quality and dont leak.

Otherwise I get all my fittings from Alert motorsport.
