The RB flash did the same thing as the cooling fan mod, but you will lose it whenever you go back to mazda for a reflash update, while the fan mod is permanent, and reversible if you buy a new coolant hose.

 

yup..correct.

 

Hey maybe the problem isn't the intake and the coolant flow it's self. It's common for our water pumps to create air bubbles in the high RPMs. Maybe you need to upgrade that it's self. Mazdamart carries a upgraded water pump. It is apparently a solution to the cavitation we all experience, some more extreme than others

 

You can also hard wire the fans to a switch. You will through a code. But it might be worth doing
