if i have a divided turbine housing and divided flange on the manifold(T4) does it matter if the gasket is just one big opening or does it need to be divided? if it needs to be divided, where can i get one? to me it makes more sense to be divided so that the gases dont cross paths.

thanks

 

I would definitely go with a devided....they sell them for $7 at ford dealerships

 

part number?

 

well i found one online, but if i can get one from the ford dealer that would be great.

 

I went from no gasket to a open gasket, no noticable difference.
