As a Radium upgrade rail, the injector interface matches OEM, so factory injectors reinstall directly and any injector upgrade must be OEM-equivalent in height and O-ring dimensions. Boosted and built F22C engines get the rail volume and port access the factory part never offered.\u003c\/p\u003e\n\u003ch3\u003eWhat You'll Feel\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eConsistent fueling to 8,000 rpm and beyond, with the 0.69\" bore holding pressure steady across all four injectors\u003c\/li\u003e\n\u003cli\u003eRail headroom ready for the supercharger or turbo the S2000 aftermarket loves\u003c\/li\u003e\n\u003cli\u003eFactory injectors reinstalled without drama in OEM-spec bores\u003c\/li\u003e\n\u003cli\u003ePort access for the plumbing, damper, or gauge the build calls for\u003c\/li\u003e\n\u003cli\u003eHardware that matches the precision of the engine it feeds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eLarge 0.69\" diameter internal bore supporting all necessary engine power requirements\u003c\/li\u003e\n\u003cli\u003eCNC machined aluminum, anodized and laser etched\u003c\/li\u003e\n\u003cli\u003eUpgrade rail: OEM injector interface, factory or OEM-equivalent injectors only (matching height and upper\/lower O-ring dimensions and styles)\u003c\/li\u003e\n\u003cli\u003eApplication-specific for the 2006-2009 S2000 (F22C, drive-by-wire AP2)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eThe Details\u003c\/h3\u003e\n\u003cp\u003eRadium's rail taxonomy draws a clean line, with upgrade rails preserving the OEM injector interface and top feed conversion rails changing injector styles entirely, and this S2000 rail is the former: injector upgrades must match OEM height and O-ring diameters and styles, with flow rates chosen by your tuner and exact part numbers confirmed with the injector manufacturer, since Radium makes no injector recommendations. The 2006-2009 model years matter here because the late AP2's fuel system differs from earlier cars, which use Radium's separate 00-05 rail. Plumbing completes through Radium's adapter fittings sized to your lines, and the usual O-ring disciplines apply: lubricate before installation, no sealant on ORB threads.\u003c\/p\u003e\n\u003ch3\u003eKit Includes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1x Anodized, laser etched aluminum fuel rail\u003c\/li\u003e\n\u003cli\u003eMounting hardware\u003c\/li\u003e\n\u003cli\u003eInjectors and adapter fittings NOT included\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e2006-2009 Honda S2000 (F22C, AP2)\u003c\/li\u003e\n\u003cli\u003eFactory or OEM-equivalent injectors only\u003c\/li\u003e\n\u003cli\u003eEarlier 2000-2005 cars use Radium's separate S2000 00-05 rail\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Radium Engineering","offers":[{"title":"Default Title","offer_id":43672695308355,"sku":"20-0391-02","price":142.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0064\/7754\/5539\/files\/radium-engineering-rad-20-0391-02-fuel-rail-only-28318275829830_39df4e52-152e-4567-a549-202450254ac3.jpg?v=1786717141","url":"https:\/\/www.tunedbyshawn.com\/products\/radium-engineering-fuel-rail-2006-2009-honda-s2000-20-0391","provider":"Tuned by Shawn","version":"1.0","type":"link"}
