NO, WB sensors have to be hot to work properly. Tailpipe sniffers are a much different deal. You CAN find them on ebay but generally, more expensive. Many of the older ones are not really "wide band."
These 'tailpipe sniffers' that you're referring to.... What exactly are they made to do? - And when you state that the wide band sensors need to be 'hot' to work, how far back from the exhaust manifolds can you go. I know they are often installed in a header collector, but is that because of ease
or is that the ideal location? - If I didn't want to mar a set of ceramic coated headers would I be as well off further downstream?
