Radium Engineering Port Injection Fuel Rail Kit for Toyota GR Supra

Radium Engineering Port Injection Fuel Rail Kit – Toyota GR Supra A90/A91 (B58TU)

Upgrade the fueling capability of your Toyota GR Supra A90/A91 with the Radium Engineering Port Injection Fuel Rail Kit, designed specifically for highly modified B58TU engines. This system adds supplemental port injection while retaining the factory direct injection system, making it ideal for high-horsepower builds, ethanol setups, and track-focused applications.

The fuel rail is CNC-machined from extruded 6063 aluminum and features a premium laser-etched finish. Injectors are positioned at a precisely calculated angle to ensure optimal fuel atomization into the intake ports. The included adapter plate also functions as an intake manifold spacer, improving packaging and overall integration.
