The 4G63 Earl Fuel Rail provides the fuel injectors on the early Mitsubishi Evolution with an increase in fuel flow.
RallySport Direct carries highly engineered products designed to improve the performance and longevity of your vehicle brought to you by Radium Engineering.
This is the Radium Engineering Early Fuel Rail for the 4G63. This fuel rail has been designed with a larger internal bore to increase the fuel volume going into your factory, or aftermarket fuel injectors. A great modification as well for those of you with larger injectors operating under a built fuel system that needs no flow obstructions under operation.
