If you could...

Flip the o2 around and look on the part you would put your wrench on.

There should be a 3 digit number.

If you could take a pic of that.. That will tell you what you have.

cant recall what it is its like 192 or something.

so is the one with the long green cover the secondary...

Yes.

Black / Black / Green / White = Primary 02.

White / White / Gray / Black = Secondary 02.

what abou the k20a3 SI o2 sensors...are they the same as the a2 sensors?

 

[suckafree]

and primary is wideband correct?

 

[RSXWhiZ]

and primary is wideband correct?

Semi-wideband. It does not read below 11.48 (which isn't really a big deal). I believe it can go as high as 30?

Peace

Actually there is more than one o2 sensor which looks the same as the primary (I think the 99-01 Civic Si uses one).

You need to go off the part number. 192400-1090

Anyone knows? I assume they will work since K pro works with them as well.

I've seen a primary O2 sensor with a blue sleeve. I'm I on crack? could have come off a DC5R or Si, I dunno...

*edit* maybe I am because I just realized that the pic katman posted is a Type R cat.
