I would not use silicone for any type of water or coolant hose personally.
Yes there's a big deal about how nice and "racey" they seem to look, at first glance.
But silicone does in fact sweat, and is not 100% water tight. Some people who run silicone radiator hoses do need to top up their coolant more often than a rubber hosed engine. Silicone hoses are slightly water permeable over time.
Read here and then decide if you want them:
Silicone Radiator Hoses: Not for the Street > MotoIQ - Automotive Tech, Project Cars, Performance & Motorsports
If you look at real race cars, or even highly stressed factory supercars, you'll see that they do not in fact use silicone for coolant hoses. Under the hood of most purpose built cars which spend more time on the track or street than car shows, you'll see plain black rubber hoses. Because they work.
I would not introduce another point of failure or reduced reliability into my car by replacing rubber hoses that work fine, with silicone which have reduced ability.
The only place silicone is of benefit is turbo piping couplers and replacing the rats nest hoses IMHO

Mazda OEM hoses are the way to go. Period. They work great, last a VERY long time, fit right, and are reasonably priced.
Zero reason to "upgrade" to silicone. Same goes for radiator hoses.
Also, you can't compare original 20 year old hoses to new aftermarket hoses. I guarantee you, give some silicone hoses 20 years and 100,000 miles and they'll look terrible and leak too.
This is something that you DON'T want to experiment with or cut corners on. Get the OEM hoses, use OEM hose clamps, and you will have many trouble-free miles.
