The fuel rail is CNC machined from extruded 6063 aluminum and laser etched, with both end ports machined 8AN ORB (3\/4\"-16), and the injectors mount at a calculated angle ensuring proper spray into the center of the intake ports without interference from surrounding components. Relocation hardware lets the OEM engine vanity cover be reused, with four adapters installing into its underside to make up for the manifold shift. Compatible with all fuel types including E85. Injectors and plumbing sold separately.\u003c\/p\u003e\n\u003ch3\u003eWhat You'll Feel\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eThe B58's DI fueling ceiling removed, with port injectors carrying built-motor demand\u003c\/li\u003e\n\u003cli\u003eA real E85 path for the single-turbo and upgraded-turbo Supra builds\u003c\/li\u003e\n\u003cli\u003eProper atomization from injectors angled into the center of each intake port\u003c\/li\u003e\n\u003cli\u003eThe factory engine bay look preserved, with the vanity cover reinstalling on the included adapters\u003c\/li\u003e\n\u003cli\u003eStock DI drivability at idle and cruise, since the kit adds rather than replaces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePIK adapter plate installs between the intake manifold and cylinder head; does NOT replace OEM direct injection\u003c\/li\u003e\n\u003cli\u003eFuel rail CNC machined from extruded 6063 aluminum, laser etched; 8AN ORB (3\/4\"-16) end ports\u003c\/li\u003e\n\u003cli\u003eInjectors mounted at a calculated angle for proper spray into the intake port centers\u003c\/li\u003e\n\u003cli\u003eAdapter plate usable as a simple intake manifold spacer without the rail (requires 2AN ORB plugs)\u003c\/li\u003e\n\u003cli\u003eVanity cover relocation hardware included (4 adapters)\u003c\/li\u003e\n\u003cli\u003eAll fuel types including E85; injectors NOT included\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eThe Details\u003c\/h3\u003e\n\u003cp\u003eTwo system notes from Radium shape the build plan. First, because the PIK spaces the intake manifold off the head, an aftermarket charge pipe will be required for the throttle body connection, so budget that alongside the kit. Second, fuel supply is a fork: the 20-0753-PK plumbing kit provides the adapter fittings and hose connecting the rail to the OEM fuel line in under ten minutes, while high horsepower builds can run an independently regulated port injection pump system instead via Radium's dedicated hanger, in which case the PK is unnecessary. The spacer-only option is a quiet bonus, letting the plate serve as a manifold spacer with 2AN ORB plugs before the fueling stage of the build arrives. Injector control via your ECU or auxiliary controller completes the system.\u003c\/p\u003e\n\u003ch3\u003eKit Includes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1x PIK adapter plate\u003c\/li\u003e\n\u003cli\u003e1x CNC machined 6063 port injection fuel rail (8AN ORB end ports)\u003c\/li\u003e\n\u003cli\u003eVanity cover relocation hardware (4 adapters) and mounting hardware\u003c\/li\u003e\n\u003cli\u003eInjectors, plumbing kit (20-0753-PK), charge pipe, and controller NOT included\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e2020+ Toyota GR Supra 3.0 (B58TU); 2019+ BMW Z4 M40i (G29, B58TU) per Radium's platform coverage\u003c\/li\u003e\n\u003cli\u003eAftermarket charge pipe required for the throttle body connection\u003c\/li\u003e\n\u003cli\u003eSupplements OEM direct injection; does not replace it\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Radium Engineering","offers":[{"title":"Default Title","offer_id":43672699502659,"sku":"20-0753","price":712.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0064\/7754\/5539\/files\/radium-engineering-28571471544390_746a3cf0-b098-498b-91c7-07cf3da45f22.jpg?v=1786717217","url":"https:\/\/www.tunedbyshawn.com\/products\/radium-engineering-port-injection-kit-2020-2021-toyota-supra-20-0753-pk","provider":"Tuned by Shawn","version":"1.0","type":"link"}
