my S475 is 1/4" npt , then the fitting i bought converted it to -6 AN for the oil feed line . in short a "T" ( twins ) 1/4" NPT for turbo then other 2 -6 AN for the feed lines .

Is 1/4" larger in ID than -4AN braided hose?

I bought -4AN but if thats too small to run from down on the block i'll have to return it and get -6.

We run -4AN on the S400's and that is fine. If you look at the actual passages that are drilled below the 1/4" NPT -4AN will feed it fine. -6AN is fine as well, just a little harder to route.

So you are also confirming that the turbo threads are 1/4" NPT?

I have physically screwed in my 1/4" NPT fitting so yes they are 1/4" . and Brayden is right -4 an is plenty , i chose 6 but still may go -4 , i thought -6 might be some extra insurance for feeding the 2 turbo's
