What is CPI? Charge Pipe Injection allows you to introduce additional fuel into a boosted application through any standard 1/8 inch NPT female connection on the charge pipe or intake, raising the overall fuelling ceiling of the setup. The system can be expanded with an injector body that features dual connections to daisy chain additional injectors from the same fuel source if required.
Important control note This is a PWM controlled injector and must be used with a port injection controller. It cannot be used without a secondary injector controller.
