I've checked on the DYI section, but I don't see any DYI for O2 sensor relocation for the new header, so I guess I have to ask via this section. I got a new header, but have to do O2 sensor relocation because O2 sensor is on the factory header near radiator and The new header have O2 hole ready which is right under behind the transmission and motor, so anyone tell me how? Do I have to cut and splice nor use tap splice longer wires or what? I appreciate for your help! Thanks luders!

assuming you got the header/downpipe combo and it has the O2 sensor hole right behind the flex pipe?? I would just go ahead and cut & splice & solder it make the wire longer to reach. As long as the O2 sensor isn't after the cat. it wont throw a code or anything.. Thats just what I would do.

Yeah, that the one near the flex pipe.... To be honest, cut/splice is what I am trying to keep avoid. I was thinking if theres any oem extended wires???

I will measure tomorrow to see if 10.5 will be enough for me. It is plug n play with 92 prelude, right?

I kept searching for ones for h22a1 (assuming that is what you have) and I keep coming up with these, and I do believe that all of honda's o2 sensors are the same plug wise with the exception of the single wire and 5 wire, if you want in the morning i can go lay under mine and tell you how many wire mine has and/or take a picture of the plug to compare

Actually its JDM F22B. Take a picture of it would be the best to see if our are the same. I might go for the 30' one because its much cheaper.

still all nasty and raining here, if my o2 was on the header I would pop it off and take a picture for you but mines right after the flex pipe also

I did this to my lude earlier this year. I didnt find anything on extendors. I think i spliced in 24 inches. It was plenty long for my f22a1. Looks like splicing is your only way, sorry man. Also i believe there connector is the same for all models. I pulled a h23 motor theother day and it had thesame o2 connector.

Did you read the thread? Theres extended wires which I am getting.

Heres the link
