Yea but the one you got from Casper most likely had the wires to link up to the power for the sensor. A conversion harness if you will. Your not gonna get that from Auto-Zone or any other locals. Seams like alot of money but make low volume parts like that harness ain't cheap. JM02
Maybe I have a freak sensor, but I have been using the same Bosch O2 since Bristol 2000. That is almost a year.
Now, I use the MaxEffort, which is not going to set a code 31, BUT the sensor still reads fine around town, at the track on or off the go juice.
I originally bought the Bosch from AutoZone b/c it came with a 3 month warranty. I figured if I wasted it, I would just exchange it for a new one, and keep doing that. Never really got into that though.
