I'm asking regarding the matter of SOHC and DOHC civics... for the part of the header, which one has 2 sensors and which one has 1 sensor?

what are you talking about? The o2 sensor?

 

yea.. sorry for not being clear.. it's the 02 Sensor.. actually it's for my shop and there's this one header from one brand that has only one 02 sensor on the header itself while Megan Racing has two 02 sensors. one on the downpipe and one on the header...

they can vary well vary.. from engine to engine and model to model, your not being specific enough

 

i'm sure it doesn't vary much right? only varies by SOHC Civics and DOHC Civics? like the one for the EX is different, but how many 02 sensors are on the SOHC's header and how many on the DOHC Civics?

or which civics were SOHC and which were DOHC?

 

its more a matter of obd.....not wether it's sohc or dohc

 

I think the 2nd O2 sensor bung on the Megan racing header is for tuning, I believe on OBD2 vehicles the 2nd O2 sensor is in or after the cat, this is why you get a Cel with a test pipe on obd2 vehicles

 

I have a 2000 civic EX and it's obd2b. It has a O2 sensor right in the middle of the cat.

 

obd2, 1 on manifold 1 cat...

ODB2 + is 2 sensors (one on cat & one on manifold or one on header and one on cat...

ODB1 is one sensor, on the manifold/header
