VEHICLE COMPATIBILITY 06-15 Audi R8 Type 42 (all GEN-1 V10 trims) 08-13 Lamborghini Gallardo LP550-2 (all trims) 08-13 Lamborghini Gallardo LP560-4 (all trims) 08-13 Lamborghini Gallardo LP570-4 (all trims) NOTES: 1. Not compatible with the 1st generation Lamborghini Gallardo 5.0L engine. 2. Not compatible with the 2nd generation Audi R8 Type-4S upper or lower intake manifold. 3. Not compatible with the Lamborghini Huracan upper or lower intake manifold. The Radium Engineering Port Injection Kit (PIK) installs between the intake manifold and the lower runners on the cylinder heads. It permits the use of port injectors for the additional fuel required for highly-modified 5.2L V10 engines. This does NOT replace the OEM direct injection system.  The fuel rails are CNC machined from extruded 6063 aluminum with a large 0.69in (17.5mm) bore. They are anodized for oxidation protection and laser etched for a high quality surface finish. Both end ports of each fuel rail are machined with 8AN ORB (3/4-16 female) threads. Anodized 6061 aluminum mounts secure the fuel rails with flat head stainless steel hardware. OEM quality gaskets are provided for sealing to the intake manifold. The PIK adapter plates can also be used as a simple intake manifold spacer without using the fuel rails. All that is required are 2AN ORB Plugs FUEL INJECTOR COMPATIBILITY 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. Below are some of the many fuel injectors that are a direct fitment.  Deatschwerks 16U-00-0042-4 Deatschwerks 16U-00-0050-4 Deatschwerks 16U-00-0065-4 Deatschwerks 16U-00-0090-4 Deatschwerks 16M-00-1500-4 Deatschwerks 16M-00-2200-4 INCLUDED -Anodized Aluminum PIK Adapter Plates -Anodized Aluminum Big Bore Fuel Rails  -Anodized Aluminum Fuel Rail Mounts  -Intake Manifold Gaskets (x 10)  -Stainless Steel Hardware   NOTES 1. Fuel injectors, port fittings, fuel hose, wiring, injector controller, charge pipe, etc. are NOT included in 20-0865. 2. See the 20-0867-03 and 20-0867-05 (below) for plumbing that provides the necessary adapter fittings, fuel filter, regulator, pressure gauge, and hose. 3. For a high horsepower port injection check out the Radium Engineering fuel hanger surge tank. 4. Because the PIK will space up the intake manifold, a minor throttle body coupler adjustment may be required. 5. Compatible with all fuel types including popular alcohol mixtures such as E85.
