have anyone tried this head
I'm planning on changing my header
so I found this 5ZIGEN ProRacer Header for B16A
but I see no spot for O2 sensor to plug in


is this normal?

if you got any recommendation for header please tell me.
I don't want my header to hit my traction bar

thx.

 

By traction bar, do you mean the OE front subframe, or an aftermarket traction bar? All headers should clear an aftermarket bar, the 2 piece units will clear the OE subframe without modification.

If you are set on that one, ask the seller for information. There should be an O2 bung there, they have them on their 4-2-1 headers. On the 2 piece unit, the bung may be on the upper portion and not shown in the image.

If you have your car wired for OBD1 O2, either upper or lower bung location will work. If you have a one-wire OBD0 sensor, you will want the sensor closer to the head. It will work in either, but with the OBD0 sensor it won't get hot enough at startup and will throw off the closed loop operation at low load if too far from the head.

 

Thank you for the reply!
I got my Innovative's pro series traction bar installed.

Also I got a FEEL'S header but I think it's for EG
seems like it's kind too long for EF
was going to custom-made a bottom piece for the header but I think it gonna hit the traction bar no matter what
