EFSiR

Any one has pictures of primaries and B pipe? Need to know the exact O2 locations on primaries and secondaries.
TIA

its about halfway down the bpipe on the headers, there is no secondary 02 sensor.

Here you go man...

It sucks having the jdm engione cause to get a header you got to find one you like the weld in the second O2 sensor, damn I am think of getting an ITR header but I don't want to cut the header, anyone knwo a way around this?

EFSiR

So, the O2 sensor with the green plug sniffs 3 and 4 cylinders and the one with white plug sniffs 1 and 2?
MOreover, which O2 sensor is Number 1?
TIA

you can just trick your ecu by splicing the two wires so that they are both connected to one o2 sensor.

The o2 sensor that is higher up on the header is the number one o2 sensor and it reads cylinders one and three, the lower one reads cyliders 2 and 4. I tried to slpice the wires together and it threw up o2 sensor ecu errors, but I have them wired right now and it runs just fine

EFSiR

Just to confirm, the higher up is the one with the green plug, right? Very slight difference on teh picture.

91sifreak - I spliced my o2 sensor wires together when I installed my JDM ITR 4-1. No codes... just takes a while for the o2 sensor to heat up.

the O2 with green plug reads 1 and 4 cylinders.
The O2 with white plug reads 2 and 3 cylinders.
The green plug goes to the USDM existing O2 plug. The extra one is the white one!
