Title: ARP part # for 1.9 AAZ head studs?
Post by: 87octane on September 18, 2009, 03:28:51 pm

Can anyone confirm if ARP 251-4701 is the correct 12mm head studs for an AAZ?
Does anyone know the proper length of stud so I can double check?

I'm not 100% positive but I think that is the only number used for the 12's on all the VW's.  It's actualy a Ford Escourt Cosworth part number, they don't have one specificly listed for us but it's the one we use. I know mine on the 1.6 is the 4701 number, I just threw the box away yesterday.

Yeah, I think the same part number is used on all 8v diesels all the way to the PD's.

In the Faq it tells us that all 12mm headed VWs are the same...11mm diesels have the same part # as the gassers...check it out and see :D
