Has anyone seen this 02 sensor?
I'm looking for the sensor on the left.
Its off my 01 b15 SE (sr20)
I've already ordered 3 and they all look like the one on the right. The problem is the threads are different sizes. Any help would be appreciated.

That's an adapter bung that comes on the roller rocker headers. PB blast it, heat it, then unscrew it from the O2 sensor and screw it back into the header.

Well thanks alot Vadim thats what I was thinking but I wasn't sure. The car has 250k on it and I'm afraid it has rust welded itself together.

Nah, it will come off. PB or wd40 and two wrenches will do the trick.

the sensor on the right looks like the one off a a33 maxima. I used one on my 94 se-r because the harness was long enough to reach from the jpipe with out being extended.

If you can't separate the sensor from the adapter bung, a dealer should be able to sell you a new adapter. It might even be available from a parts store.

I really didn't try. I didn't want to destroy the old sensor by mistake since I was taking a road trip.
