+1 I would save yourself from headache and get the 'enhanced' one. The stock replacement will only fail in due time.

Edit here is a link, they sure are way over-priced though imo.

45$ enhanced valve pin for aea.

I would make this myself for 10$ or less in under an hour personally, but that's just me!

The seller on eBay does accept offers ….. let me just say he won’t take 30 for it.
