Exclusive fitment for the 2020+ C8 Corvette Stingray LT2!!!

The plug-and-play CR-Fueler is a port injection controller that adds a secondary set of 8 (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 of ALL GM V8 direct injection equipped vehicles from 2014-2019. Including L83, L86, LT1,LT2, LT4 and LT5 engines.


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.
