Radium Port Injection Fuel Rail Kit - Toyota Supra A90 19+/BMW Z4 G29 18+

Radium Port Injection Fuel Rail Kit - Toyota Supra A90 19+/BMW Z4 G29 18+

Application: 2020+ Toyota GR Supra (A90/A91) and 2018+ BMW Z4 (G29) – B58B30O1 (B58B30B), B58B30M1 (B58B30C) and B58TU engines
Part Type: Port injection kit (cylinder head adapter plate and fuel rail)
Part Number: 20-0753

The Radium Port Injection Kit (PIK) is an adapter that sits between the intake manifold and the cylinder head, permitting the use of port injectors for the additional fuel required by highly modified B58 engines. It does not replace the OEM direct injection system, and the adapter plate can also be used as a simple intake manifold spacer without the fuel rail by fitting 2AN ORB plugs.

The fuel rail is CNC machined from extruded 6063 aluminium and laser etched, with 8AN ORB (3/4"-16 female) threads in both end ports. The injectors are mounted at a calculated angle to spray into the centre of the intake ports, and relocation hardware (four adapters under the cover) lets you reuse the OEM engine cover. Compatible with all fuel types including E85.
