I put the Bosch o2 sensors with factory plugs in my rodeo a few months ago and they are working fine. My mileage went up a bit after replacing the originals that had 100k miles on them. I've never been a fan of Bosch but havent had problems with their stuff on the rodeo. The ones I had in the mitsu were some off brand I think.
