Difference in bypass valves?

Does anyone know what the difference is in the Bosch bypass valves with part numbers:

-0 280 142 108
-0 280 142 110

I can only find the 110. Just want to make sure there isnt a boost restriction or something on one versus the other. I have read that people on here have used both but I'm just curious before I order one. Thanks, Ryan

That looks good. There's a part # for the Porsche part that can hold a few extra psi before leaking, but it might be obsolete at this point. They are bascially all the same in that series.

From everything that I have run across, the 110 is the better of the two. You're good to go.

Thanks guys. Its on the way!

I read up and found the 110 is supposed to be the better one. That's what I have.

If I could, do I have it mounted correctly?

Yup you have it orientated correctly, as long as the nipple for the vacuum is in line with the discharge tube and NOT perpendicular you are good to go......

Thanks 5150, you're a lifesaver
