{"product_id":"radium-port-injection-kit-k20c1","title":"Radium Port Injection Kit - K20C1","description":"\u003cp\u003eThe 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, as shown in the below picture. It is compatible with all fuel types including popular alcohol mixtures such as E85.\u003c\/p\u003e\n\u003cp\u003eThe 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 8AN ORB (3\/4-16 female) threads. Note that the 2 top fuel rail ports will need to be plugged with \u003ca href=\"https:\/\/www.radiumauto.com\/products\/8AN-ORB-Fittings\"\u003e14-0150\u003c\/a\u003e unless the plastic OEM wiring harness carrier is modified (see below).

The injectors are at a specific angle to ensure proper spray into the intake ports.\u003c\/p\u003e\n\u003cp\u003eThe fuel rail features four threaded ports that are all tapped for 8AN ORB.\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eIf building a custom fuel setup, appropriate fittings must be selected based on the specific application. Ample space around the fuel rail port(s) is necessary for larger accessories such as fuel pressure regulators, fuel pressure gauges, and fuel pulse dampers.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNOTE:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eFuel injectors, port fittings, fuel hose, wiring, injector controller, etc. are NOT included.\u003c\/li\u003e\n\u003cli\u003eBecause the PIK will space the intake manifold off the head, a custom throttle body pipe will need to be fabricated.
