{"product_id":"555cc-high-impedance-side-feed-fuel-injectors","title":"555cc High Impedance Side-Feed Fuel Injectors","description":"The Nismo 16600-RR543 is a set of side-feed, high-impedance fuel injectors designed to provide increased fuel volume for performance-tuned engines, specifically those running boost levels above 15 psi. While labeled as 555cc by the manufacturer, these injectors are widely regarded in the enthusiast community as 615cc components, with independent testing confirming a flow rate of approximately 600cc at 3 bar of fuel pressure.\n\nThese injectors are designed for the 1995-1996 Nissan 300ZX Twin Turbo (Z32). For earlier models, installation requires the use of an early-to-late style fuel injector adapter kit. Please note that these injectors are not intended for use without appropriate engine management tuning to account for the increased flow rate. Professional installation and custom ECU tuning are recommended to ensure safe engine operation and prevent lean conditions.\n\nEngineers designed these units as a direct performance upgrade for Nissan vehicles including the 300ZX (Z32) and RB25DET-equipped Skyline R33 models. As these are high-flow performance components, ensure your fuel system's remaining hardware is compatible with higher fuel delivery requirements.","brand":"Nismo 555cc","offers":[{"title":"Default Title","offer_id":52663114924344,"sku":"16600-RR543","price":1026.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687515409.jpg?v=1784323945","url":"https:\/\/store.motormia.co\/products\/555cc-high-impedance-side-feed-fuel-injectors","provider":"MOTORMIA","version":"1.0","type":"link"}
