I've checked all the "3 wire" and "heated o2" threads and can't find an actual part number...either GM or Bosch...or what year/vehicle to ask for.
Thanks,
SC

GM#25312179 or alternately, AC Delco#AFS74
From a 1995 S-10 4.3L vin "Z"

Dunno why you'd want to use Bosch stuff in a domestic vehicle. European parts cause all kinds of wierd problems in domestics. Same goes for Autolite (Ford) and Champion (Dodge)

Thanks for the numbers. I've used Bosch before...no probs, but will go with genuine GM this time. Thanks again, SC
