You could replace just the boot. My recommendation is to replace the entire AOS with the OEM part.

How do I know this? There are minds far sharper than mine on this forum, and I listen.

Are you throwing any codes? Mine (1124/1126/0150) have been absent since the AOS replacement.

Perhaps one of those sharper minds can confirm my diagnosis.

Thanks for the quick response. No codes surprisingly. No major smoke except the occasional start-up puffs. As I read more about the AOS failure and other horror stories, my main question now becomes can/should I continue to drive it? This is my daily driver.
