Show original supplier description
The Precision Raceworks Multi-Port Injection Kit is a high-performance supplemental fuel delivery solution engineered for BMW B58 Gen 1 and Gen 2 engines. When upgrading turbos or pursuing power levels beyond the limits of the stock fuel system—typically around 600rwhp on 93 octane—this kit provides the additional headroom required for safe and consistent operation on various fuel types, including full E85. Technically, the kit features a plate-style design that ensures diagonal, equal fuel distribution across all six cylinders. It includes genuine Bosch 750cc injectors (at 43.5psi), which flow over 1000cc at 72psi, all flow-matched to within 2% or better by an independent lab for optimal tuning accuracy. The fuel lines are constructed from smooth-bore PTFE with stainless and nylon braiding for maximum durability. The kit also utilizes OEM-spec manifold gaskets and full stainless steel hardware for a reliable installation. Installation requires an aftermarket 2-piece charge pipe to ensure proper clearance and fitment. Common controllers used for this platform include the Split Second AIC-6 Controller or the Motiv Re|Flex Controller. Please note that this product is not for sale or use in the state of California on any pollution-controlled vehicle as per California Air Resources Board regulations. Users should confirm that their specific B58 engine configuration is compatible via the vehicle selector.
