Does anyone know the stock Diameter of the BOV Hose? I just bought a Greddy Type S BOV and I need to now get an adapter flange for it but don't know the correct size. I did a search but couldn't find anything.

Thanks in Advance

I'd like to know this as well, and also the diameter of the turbo outlet, and stock latex intercooler pipe.

I've got an idea. Measure it.

I don't have an X, can you measure it?

same size as your upper rad hose.

i think its 1.375" (1 3/8)
