Unlike the side-feed conversion kits, this upgrade set assumes top feed from the factory, keeping the install a direct swap. All fuel types including E85.

Plumbing completes through Radium's EJ rail plumbing kits, series or parallel per the build (noting those kits' own fitment rules), and the injector rule is the standard, OEM-equivalent dimensions confirmed with the manufacturer.\u003c\/p\u003e\n\u003ch3\u003eKit Includes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e2x Anodized, laser etched high flow top feed fuel rails with mounting hardware\u003c\/li\u003e\n\u003cli\u003eInjectors and plumbing sold separately\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e2004-2014 Subaru WRX and 2004-2021 STI with factory top feed injectors (verify injector style)\u003c\/li\u003e\n\u003cli\u003eSide-feed cars use the Radium 20-0568 conversion kit instead\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Radium Engineering","offers":[{"title":"Default Title","offer_id":43672707432515,"sku":"20-0569-02","price":237.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0064\/7754\/5539\/files\/radium-engineering-rad-20-0569-02-30296844861510_b312387b-e786-4e88-8cc7-824331603665.jpg?v=1786717370","url":"https:\/\/www.tunedbyshawn.com\/products\/radium-engineering-subaru-ej-top-feed-fuel-rail-upgrade-2004-2014-subaru-wrx-and-2004-2021-subaru-wrx-sti-20-0569-02","provider":"Tuned by Shawn","version":"1.0","type":"link"}
