Near-perfect replacement
After removing the original sensor that had failed, I installed this one, using the original wiring/plug.

The sensor body is identical to what was removed.This was a fraction of the cost of a ready-to-install sensor, but it was well worth the effort to do a little work.The only criticism is that the shrink-tubing provided to seal the splices seemed to take longer than I expected to shrink down.

Best O2 at Best Price Around
I still have yet to find a cheaper place to buy a 4-wire denso O2 sensor than here at Amazon. I never thought I'd be buying car parts on here, but if they want to sell it, I'm happy to buy it.I replaced my Celicas sensor with this universal one in about 15 minutes using a socket I already had. The check engine light I had previously has disappeared & my fuel economy slightly improved. This is the same brand that most japanese manufacturers use as OEM equipment, such as Mazda, Toyota, Nissan. I've used Bosch universals in the past & this one is equivalent, but less expensive than the Bosch 4-wire counterparts.
