17+ Civic Port Injection Fuel Kit By Radium
**This does NOT replace the OEM direct injection system.**
**Fuel injectors, port fittings, fuel hose, wiring, injector controller, etc. are NOT included and must be sourced elsewhere.**
**PIK will space the intake manifold off the head, a custom throttle body pipe will need to be fabricated. Alternatively, a silicone coupler can be used with OEM throttle body pipe.**
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.
The kit includes the PIK adapter plate, custom fuel rail, fuel rail mounting hardware, and OEM Honda gaskets, as shown in the below picture. 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.
Note that the 2 top fuel rail ports will need to be plugged unless the plastic OEM wiring harness carrier is modified.
