I have been putting this off for far too long in my track rat. When I replaced the stock cast iron manifolds with HPC coated Comptech headers, I ruined the original oxygen sensors removing them from the boat anchors. Bummed, I tried my AEM wideband sensors in the 1v mode. No good. Car would crank, but die when throttle was dropped, and throttle tip in was delayed. Tried the AEM ecu with the DAL motorsports program, slightly better but still not driveable. At the time (mid 2004), there were no documented success stories using non OEM replacement sensors. I had already spent a boat load of money on this supposedly "cheap" track car project, which is now not even running
Plus, I had dented the red car's driver side rear fender and torn the bumper cover the month previous. I was having a hell of a time getting the yellow koni's back on the red car, so my summer was looking like it was going to be NSX less. Since I had become a cheap bastard, it became a NSX less year.
Sorry about the rant. After reading a couple of good posts on using the generic oxygen sensors for replacements, I ordered two from www.oxygensensors.com I ordered two of the generic oxygen sensors and received them in 3 days. The part number is 250-24200 and is made by Walker. They cost less than $60 a piece versus $200+ for the Acura part.
You receive a nice standard oxygen sensor with four bare leads, crimp connectors, heat shrink connector covers, and copper high temp thread dressing.
Cut the OEM connector and wires from the old sensor. Strip the ends of the wires bare approximately 1/2" for all four wires.
Using the included crimp connectors and the self explanatory wiring diagrams, connect OEM white to Walker Blue, OEM green to Walker white, and black to black and black to black. Cover with heat shrink tubing and using a heat gun cover the connections.
Now install according to the NSX manual and you are good to go. Car cranked and ran just fine with the OEM ecu back in the car. That is until the car died on the back esses at Barber last weekend. (See related thread at some point, but unrelated to oxygen sensors).
