Does anyone know if these work or not?

 

Not sure, would like to know though, I need a set.

 

sure they are just resistors you can buy them at radio shack for abotu 1 buck

 

I would just spend a few more bucks and get the real thing from Casper and avoid hacking your wiring with those things. JMO though.

 

Or you can program them out when you do a tune.

 

Thats all dependent of course on his emissions regulations.

 

I would honestly go with the tune, those 02 sims wear out anyway.

 

Tuning them out is the easiest route, but then all that is going to do is post a Not Ready status. Assuming you have deleted your AIR and EGR, as well as the Rear O2s, you have already failed the OBD-II emissions test in many states.

 

Will not work for LT1. Reported working for 3800-II.
