    ID of stock UrS4/6 MAF

    I'm being lazy but to save stripping down my boost pipes as my MAF is on the pressure side has anyone got an exact internal diameter measurement of the S4/6 MAF.

    Preferably from some literature or very accurately measured.

    Thankyou in advance

    80mm from memory.
    I can measure mine tomorrow...

    EDIT:
    That was external...
    I will look at the internal diameter.
