Improved Fuel Injector {1251, 1254, 1290, 1713}

Usage:

C6.6 666
Engine:
C6.6 (S/N: 666825-1510)

There is a potential risk of cracks in the fuel line connection of the fuel injector.

An improved fuel injector has been introduced. The interference fit between the edge filter and the fuel injector body has been optimized in order to reduce the stress in the assembled fuel injector body. The improved injector overcomes the possibility of cracks in the fuel line connection.
