Direct injection engines offer numerous advantages over port injection engines. The main advantage is better atomization of fuel entering the combustion chamber. Direct injection also requires a significantly higher pressure to atomize the fuel properly which can cause components of the fuel system to fail over time. Clogged fuel injectors can cause a variety of performance issues including misfire and power loss.


N54, N63, and S63fuel injectors have an index number which is critical to take note of when it\'s time to replace a failed fuel injector. The index number dictates on whether fuel injectors can be mixed or not. These fuel injectors are the most recent version of what\'s available and can only be installed with other fuel injectors that have an index number of 11 or higher. If the injectors are 10 or lower all fuel injectors will need to be replaced to ensure proper fuel system and engine performance.


Note: When installing new injectors a calibration must be carried out. The adjustment value must be read off the injector before installation and noted. This adjustment value will be needed later on when the calibration is carried out. The injector has a protective cap on the tip of the injector which keeps the tip clean from contaminants and keeps the viton seal compressed. Leave this cap in place just prior to installation as the seal will expand making installation impossible without the special dies to compress the seal.
