A longer life of casting by increasing the strength of the casting via adding more alloy element.
Caps are in tight specification and in line with concentricity, without any interfere with camshaft
Installed with newest steel injector tube to prevent leakage.
The joint surface has been performed with smooth transition. This improvement will effectively avoid the leakage caused by the crack on those joint surface under high temperature.
Flat (copper) and Conical (stainless steel) type injector cup are both available.
