hi, just wondering if anyone has any information about blocking off the EGR system either in the center plate or the manifold on a factory 12AT?
is there any benefit to it?
i would think that the manifold would run cooler as it doesn't have hot gas going into it but will it have any adverse effect on the engine?
can it be blocked further down in the actual plate before the manifold?
any help would be appreciated,
thanks.
Jex.

 

12A-T doesn't have EGR, so one less thing to do

 

not sure but what is the square port in the middle of the manifold below the centre inlet port for?

 

Air control check valve otherwise known as the ACV.
