So are the generic O2 sensors several list vendors sell (I bought mine from
Bus Depot) legit or not? I've read on GoWesty that the generics do not work
well or at all on the Vanagons and another list member told me he didn't
have good luck with his generic either. I had a a generic Bosch installed on
my van about 2-3 weeks ago and it really hasn't been running that good
since. I'm wondering if I wasted money by trying to save money and will end
up paying more in the long run when I buy the real deal. Any thoughts?
