Can you guys give me your best argument for why you can or can't install the O2 sensors in a primary tube (one on each side) vs. the collector?????
I have always heard that putting them in the collector from the 10 - 2 o'clock postion is best....and have always done that.
However, that is tricky to do with twin sensors (right & left bank) - and I don't know if it has to be done.
Here is a picture of the type of headers I'm running - just to give you a better idea. If put in the primary, it would be in a staight section half way betweent he collector and header flange.
So...give me your best educated guess
