Radium: FUEL RAIL PLUMBING KIT : Toyota GR Supra / BMW Z4 (G29) : 20-0753
The Radium Engineering Port Injection Kit (PIK) installs between the intake manifold and the cylinder head. It permits the use of port injectors for the additional fuel required for highly-modified B58TU engines. This does NOT replace the OEM direct injection system.
The fuel rail is CNC machined from extruded 6063 aluminium and laser etched for a high quality surface finish. Both end ports are machined with 8AN ORB (3/4-16 female) threads.
The injectors are mounted at a calculated angle to ensure proper spray into the centre of the intake ports without sacrificing interference from surrounding components.
The PIK adapter plate can also be used as a simple intake manifold spacer without using the fuel rail.
Relocation hardware is provided to allow the OEM engine vanity cover to be reused.
