Radium Engineering Port Injection Kit for 2020-2022 Toyota GR Supra and BMW Z4 (20-0753)
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits 2020-2022 Toyota GR Supra and BMW Z4 M40i models with the B58 engine.
The Radium Engineering Port Injection Kit (MPN: 20-0753) provides a precision-engineered solution for adding secondary fueling to high-output B58 engines. As owners push the limits of the factory direct injection system, this port injection kit allows for the additional fuel volume required for high-boost applications and alternative fuels like E85.
The core of the system is a CNC-machined injector plate designed to sandwich between the factory intake manifold and the cylinder head. This design ensures proper injector spray angles into the intake ports without requiring permanent modification to the OE manifold. The kit includes a high-flow fuel rail and necessary hardware to secure the assembly to the engine.
- Specifically engineered for the B58 engine platform
- Precision-machined sandwich plate retains factory intake manifold geometry
- High-volume fuel rail with 0.69-inch internal bore for consistent pressure
- Includes all necessary gaskets and mounting hardware for installation
- Manufacturer Part Number: 20-0753
- Note: Fuel injectors are NOT included; must be sourced separately
