you could buy a bosch universal 4 wire o2 sensor and just wire it up can buy at advance auto or any other auto parts store runs like 60$ and no i would not by used. just my .02

anyone else?

yeah you probally got to extend your wires since you went from odb1 to odb2 which honestly id just buy a jumper harness and go to ob1 more tuning options there than you could have your second o2 sensor turned off in the tune.. do some research... can't stress enough search search and search some more

Try amazon, I got a denso brand off there pretty cheap for a friend recently. Very similar to OEM and its free shipping from Amazon.

I got mine for about $40 bucks at www.sparkplugs.com and they work great and shipped fast! Def recommend you check them, they have superb prices.

"They will fit any obd1/2 Honda, but may require a O2 sensor extension harness."

that's what their site says, but you may want to call them if you have some doubts seeing as you need the secondary and I'm assuming this is for a primary. Also you should measure your length wire to make sure its long enough as well.

extra cam needed

The secondary o2 is part of the cabin harness. That's the hard part of bar'n an obd2 engine in an obd1 car out here in Cali. There's info around for knock sensor, ckf sensor, vtec hook-up and everything else but, I haven't seen one for the secondary o2 yet

k thanks did you get the OE or the universal? and would i order it under the motor (01 integra gsr) or under the chasis (94 civic hatch cx)?

k i will call them when they open and ask.

yea i cant really find any info on the o2S sensor. this is fn confusing
