I have a lightly used O2 sensor for sale. It is the OEM-style from NTK, meaning it has the wires already hooked into a plug and play connector. The sensor has about 5000 miles on it and works fine. I'll clean it with some electronics cleaner before I ship it to you just to be safe.

Will fit all 94-01 Integras, OBD1 or OBD2 (for front or rear sensor). May also fit other Hondas.

The insulation on the wiring has started to come apart, but this is easily fixed with some electrical tape or whatever.

Retail price at the dealer is $250. I'm letting this go for $50 shipped.

(in case you're wondering why I'm selling, it's because I thought the wires had been destroyed by a questionably-placed O2 bung, but that wasn't the case so I bought a new one and installed it for nothing)

 

Bizzump.
