The plug-and-play CR-Fueler 3.0 is a port injection controller that adds a secondary set of 6 (or more) port injectors to increase the overall fueling capacity. This allows for higher ethanol mixtures, more boost, and safer, more reliable horsepower. It can be configured with many options, with coverage for

LF3-LF4 Twin Turbo V6.


As an added benefit to the port injection, the fuel being sprayed onto the intake port walls and valves, will clean the harmful deposits that will build up in Direct Injection only engines intake tract.

All of this at a much better value then larger Direct Injection High Pressure Fuel Pumps or injectors, with no idle or low speed driveablity issues that can be associated with those parts.

No ECU included in base price! You must select the ECU choice during checkout for a complete controller kit!
