BAC valve coolant hoses?

Forward hose goes to water pump housing. Rear goes to thermowax pellet.

Autozone/checker hoses will not fit correctly because they are not metric. Cleanest easiest is to use mazda. Pricey yes but fit right and will not leak. Using metric hose would be my only other option. That way you can stay with the spring clamps.

Thermal pellet is for cold start. Effects driveability and emissions(during warm up).
Removing it can be hard on the motor because it does not come to full operating temps a fast, especially for a daily driver. In the long run it can shorten engine life.

Race cars not so much because you are usually sitting in the car holding it at 1500/2000 for a while.
