Well a 4th gen h23 o2 sensor work on a h22 4th gen car? If know one knows the answer then ill find out next week when i finally get my downpipe. Thanks to a HT friend. Anyways...i just wanted to knwo if i could use my h23 o2 sensor for the h22 i just put in my car. just so i can prepare for the pipe downpipe install.

 

I'm using my h23 o2 sensor on my h22. It is probably the same part. No problems here.

 

all honda/acura 4wire o2's are all interchangable

 

Thanks guys!
