165 Intake Manifold

Inlet to plenum chamber. Note the CSI injector in the centre Cleaned and deburred intake Another view Whole manifold including TVIS assembly
Cleaned and ported manifold FPR VSV located on the rear of the manifold. It's a pig to get at, if you remove the manifold then I suggest that you don't put it back here! Close up of the FPR VSV. This is used to prevent problems with re-starting and idle speed stability when the fuel temperature gets very high. The 165 is the only GT4 to have this VSV
