Thread: WBO2 Sensor Holley Terminator - Left Or Right

    Default WBO2 Sensor Holley Terminator - Left Or Right

    Getting ready to drill & weld the receptacle for the Holley Terminator EFI wideband oxygen sensor. Anyone who has used one, or anyone for that matter, have any recommendation to mount on the left or right side pipe. I'm thinking left/driver side? Car is a MK IV, Factory Five Cobra. Ford 427/W. 4 into pipe.

    It really doesn't matter...either side will work fine.

    Find out if your engine has any particular common cylinder issue.
    Example: Some Chevy engines seemed to always have issues with cylinder 8 being a hot spot.
    Most people who put a hole in a piston or pushed water, found the issue happened at cylinder #8.
    So in that case, I would put the WBO2 on the passenger side to try to monitor that side closer.

    That's good advice. Also, some engines inherently run a little leaner on one bank.
    If you know which bank of your engine it is, install the WBO2 sensor in that bank.
