Radium Engineering Toyota MK5 Supra Port Injection Kit

When a Gen 2 B58 is built well past stock power, the factory direct injection can't supply all the fuel it needs. Radium's kit adds a set of port injectors to carry the extra fuel. It works alongside the factory direct injection rather than replacing it.

What you get

• Adapter plate that installs between the intake manifold and the cylinder head. It can also serve as a plain manifold spacer without the fuel rail.
• CNC-machined 6063 aluminum fuel rail, laser etched, with 8AN ORB threads at both ends.
• Angled injector mounting so each injector sprays into the center of its intake port without hitting nearby parts.
• Relocation hardware so the factory engine cover still fits after the manifold shifts.

Good to know

• Injectors are not included.
• Feeding the rail from the factory low-pressure line takes Radium's separate plumbing kit. That kit isn't needed if you run an independent port injection fuel system.
