Leaded fuel poisons ANY of those sensors.. plain and simple. Doesn't matter if it's NTK or Bosch.
The NTK sensor most of them use is from a Honda Civic.
The Bosch.. similar to what is on a Cadillac Catera or a VW Golf GTI. Whoever is telling you one is good for leaded fuel is pulling your chain.. and making an extra buck. Have them send you the spec sheet from NTK.. you'll see. I have it.

They get a bit more technical than the rest.
