[Es2] MAF - turbo hose for tight clearance RS2 turbo in Coupe Quattro.

[Ben Swann]

Thanks Matt,

I believe the hose you reference is same as mine from the 3B.  I am able to get it on,
but it does rub.

I'll toy with that as well as other possiblities.

Cheers!

Ben here are some better pictures I took with the headlight out.  The Bailey valve goes
on the headlight side of the support, and the N75 valve is attached using a 2" length of
1/4" copper tube on the center side.  I tie-wrapped the tube to the IC crossover pipe to
keep the hose nipple from rubbing on the support.  There is zero contact on any rubber
bits and I saw no wear whatsoever.

the p/n of the hose I have is 034 133 357N and the turbo is K24.

Good luck!

-Matt
