They come with a small tool to remove the valve core, screw in extender, remembering the PTFE tape, then re screw the core back into the extension. Simples.
Extinction is the rule. Survival is the exception.
The vittorias are super easy with extenders. Take valve off, put 40mm extender on, put valve on top of extender. No need to remove valve cores or anything.
+2 for PTFE Tape, I had the same issue on my Conte tyres and Zipp extenders. Slapped a bit of tape on the existing valve, screwed on the Extender and no more leakage (go Kev.)
