Show original supplier description
The Precision Raceworks Port Injection Kit provides the supplemental fueling capability required to support high-horsepower builds, reaching up to 1,000whp. By moving beyond the limits of the factory fuel system, this kit enables the safe use of ethanol blends and high-performance tuning. It includes six genuine Bosch Motorsport injectors that are static and dynamic flow-matched to a 2% variance, ensuring reliable and precise fuel delivery. Each kit is supplied with a certificate of conformance for tuning optimization. The system is engineered for a seamless, factory-like aesthetic once installed and utilizes a smooth-bore PTFE fuel line with stainless and nylon braiding for compatibility with all fuel types, including E85. The included stainless hardware and OEM-spec manifold gaskets ensure a robust, leak-free connection. Please note that an aftermarket 2-piece charge pipe is required for installation, and users must pair this kit with an external injector controller, such as the Split Second AIC-6 or the Motiv Re|Flex controller. This product is not for sale or use in California on any pollution-controlled vehicle as per the California Air Resources Board. Fitment covers a wide range of BMW B58 Gen 1 and Gen 2 applications including the M240i, 340i, 440i, 540i, 740i, 840i, and various X-series models, as well as the Toyota MkV Supra. Please verify your specific model and trim for complete compatibility.
