Radium Port Injection Kit | 2017+ Honda Civic Type-R (20-0428) Radium Engineering

Honda K20C1 Port Injection Kit by Radium Engineering

The Radium Engineering Port Injection Kit (PIK) installs between the intake manifold and the cylinder head and permits the use of port injectors to add additional fuel for high-horsepower modified K20C1 engines, commonly found in the FK8 Civic Type-R. 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. It is CNC machined from extruded 6063 aluminum and laser etched for a high quality surface finish. All 4 ports are machined with an 8AN ORB (3/4-16 female) threads.

Machined phenolic 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, as shown below.

This kit is designed for specific top feed fuel injectors with upper and lower O-ring spacing, as depicted below. The upper and lower injector O-rings must be 14mm diameter. The included fuel rail mounting brackets permit 2 different height fuel injectors to be used, as shown below.
