A couple of months ago I had hooker long tube headers put on my 93 z28 and Ive been thinking about converting my single prong 02 sensors to the 4 prong heated sensors. I was wondering if anybody has tried the kit on the link below, or if I should get a something different.

Shoebox has a wiring diagram:

If you haven't visited his site before, its a treasure trove of LT21 information.

Thanks, I was just looking at that site, and there is a lot of info that should be useful to me. And I guess if nobody has tried that brand of o2 sensors, I will probably go with gm's.

 

Ive got one more question. When I get the sensors will any post 93 lt1 sensors work?

 

Shoebox's wiring diagram includes the original 94-97 pre-cat sensor number = 25312184. That number was superseded with part # 19178930. Also known as AC Delco (Delphi) part # AFS75.

 

Thanks
