Short-lived Subara clutch cylinders

I have a 2000 Outback and have had to replace both the clutch master and slave cylinders twice since I have owned this car. The last pair only lasted 24,000 miles for the master and 18,000 miles for the slave. Is this unusual?

No, what kind of parts are being used to replace, aftermarket specials or OEM Subaru?

The Subara clutch cylinders are known to be unreliable…

Supposedly OEM.

Hmm…The original ones lasted 78,000 and 83,000 miles.
