Re: Heated O2 sensors

Shawn -

on the subject of heated 02's...
I got some from the the gnttype.org site's list of parts suppliers - theres
one guy on there who is the parts manager at a GM dealer in ohio - I forget
the name - I posted about this before and did not have the name then either.
the guys last name is the same as the dealership name I think his dad owns
it maybe? anyway he has a kit for the buick GN that he put together
consisting of a heated o2, and a conversion set of connectors that take a
standard GM o2 connector and mate it to the heated one, you just connect a
ground and ignition power source up as well. looks factory enough. I have no
part numbers I just called and said "you supposedly sell a heated o2 kit for
buick GN's can I have one" they are cheap too like 39 cause as a GN lister
you get 10% above dealer cost.  I REMEMBER his name is ZAK i think.
