radium ENGINEERING Port Injection Kit (2019-2022 BMW Z4 & GR Supra 3.0T)

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 aluminum and laser etched for a high quality surface finish. Both end ports are machined with 8AN ORB (3/4-16 female) threads. For a list of all 8AN ORB adapter fittings, go HERE.

The injectors are mounted at a calculated angle to ensure proper spray into the center of the intake ports without sacrificing interference from surrounding components.

Compatible with the 2nd generation B58TU engines listed below.
-B58B30O1 (B58B30B)
-B58B30M1 (B58B30C)
NOT compatible with the 1st generation B58B30M0 (B58B30A) engine.
