Radium Engineering 2017+ Honda Civic Type-R Port Injection Kit

The Radium Engineering Port Injection Kit (PIK) installs between the intake manifold and the cylinder head. It permits the use of port injectors to add additional fuel on high-horsepower K20C1 engines. This does NOT replace the OEM direct injection system. The kit includes the PIK adapter plate, custom fuel rail, fuel rail mounting hardware, and OEM Honda gaskets. It is compatible with all fuel types including popular alcohol mixtures such as E85. The fuel rail features a large 0.63" internal diameter bore, is CNC machined from extruded 6063 aluminum and laser etched. All 4 ports are machined with 8AN ORB (3/4-16 female) threads. Insulating mounting spacers and washers are included to completely isolate the fuel rail from heat created by the cylinder head and transferred through the mounting bolts. The injectors are at a specific angle to ensure proper spray into the intake ports. Fuel injectors, port fittings, fuel hose, wiring, injector controller, etc. are NOT included. Because the PIK will space the intake manifold off the head, a custom throttle body pipe will need to be fabricated. Alternatively, an offset silicone coupler can be used with the OEM throttle body pipe. The kit is compatible with 14mm upper and lower o-ring universal fuel injectors, in either 34mm short body or 48mm medium body heights.
