Port fittings are selected per your plumbing plan, factory-style or full AN, with Radium's ORB adapter catalog covering both paths and the usual O-ring lubrication discipline throughout. Injector upgrades follow the standard rule, OEM-equivalent dimensions confirmed with the injector manufacturer, flow rates from your tuner.\u003c\/p\u003e\n\u003ch3\u003eKit Includes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1x Anodized, laser etched high flow fuel rail with mounting hardware\u003c\/li\u003e\n\u003cli\u003eFittings and plumbing sold separately\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1989-1993 Nissan 240SX (S13, KA24E)\u003c\/li\u003e\n\u003cli\u003eKA24DE engines use Radium's separate rail\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Radium Engineering","offers":[{"title":"Default Title","offer_id":43672701730883,"sku":"20-0558","price":218.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0064\/7754\/5539\/files\/radium-engineering-rad-20-0558-29454193721414_651152ab-ba59-42fa-a2e1-4d0e28c01e1c.jpg?v=1786717258","url":"https:\/\/www.tunedbyshawn.com\/products\/radium-engineering-fuel-rail-kit-1989-1993-nissan-240sx-20-0558","provider":"Tuned by Shawn","version":"1.0","type":"link"}
