    How do the front O2 sensors relocate? The front bungs are capped because they're in the wrong place for this application, and it looks like there are 3 bungs on the Xpipe? They seem too far back to be properly registering as front bank sensors.

    Asked by: JimmyM
    From Flowtech - For our EFI system to get a good accurate reading, the o2 sensor has to be mounted about 6-8in after a collector and have at least 18-24in of pip after it to prevent reversion.
