    Only on later VTRs, you need to make sure the mani clears the plastic filter housing, or alternatively convert it to a mk1 oil filter setup

    You dont always have to, it depends on which manifold you have and if it clears the plastic housing or not

    IIRC sportex do one for the later vtr's that clears the housing

    Im not sure if the Janspeed clears it

    Don't hold me to either of those though, if you are going for one then it will be best to ask the supplier. Although tbh it isn't a major job to convert it to the mk1 setup

    ive got a piper 4-1 manifold and that fits without moving the oil filter
