    What is the I.D. of these two pipes...

    Guest-only advertisement. Register or Log In now!
    I want to replace them, however, I want to ensure I have the correct I.D. pipe in my "big old box of Audi pipes"

    I will buy a oem one if needed, but a quick DIY would be nice. Both hoses have small cracks on them and are most likely baked on...so as I attempt to remove them to check the I.D. myself, they will most likely self destruct....and If I do not have the correct size...im FUBAR

    last...are they both the the same I.D. at both ends?

    Both live right here...




    and the pipes...



    and the 2nd..




    Thanks all

    The first one is going to the combi valve. Part of the SAI system. The second one if the block breather connecting to the PRV.

    Just follow where they go to answer your own question, the top one goes to the "pancake" at the back of the valve cover ie: PRV. The lower to the combi, you have the part numbers clearly pictured, Google will tell you which is which. You can get silicone replacements for about $12.
