{"product_id":"42-lb-hr-disc-high-z-fuel-injector","title":"42 lb\/hr Disc High-Z Fuel Injector","description":"The Racetronix 42 lb\/hr Disc High-Z Fuel Injector (MPN: FJ-SM-12S) is designed for high-performance applications, serving as a direct replacement for specific Ford\/Bosch part numbers. Unlike traditional pintle injectors, this disc-type injector utilizes a revolutionary design that offers numerous performance and longevity benefits.\n\nKey advantages of this injector, as noted by Delphi, include a flat mating surface that prevents excess fuel evaporation and subsequent deposits or clogging. It is also compatible with alternative fuels such as E85 and Methanol, boasts a longer service life, and features a high-speed disc action for a wider dynamic flow range, leading to improved idling performance and quieter operation. The disc design actively resists build-up, ensuring consistent fuel flow and preventing leakage for quicker starts.\n\nTechnical specifications include a static flow rate of 42.29 lb\/hr (n-Heptane) with a tolerance of +\/-4%, and a dynamic flow of 9.96 mg\/pulse with a tolerance of +\/-6%. It operates at high impedance (12-16 ohms), making it compatible with all factory ECM\/PCM injector drivers. The injectors are dynamically flowed and grouped to within 1% tolerance when purchased in packs, tested with n-Heptane at 20°C, 3.0 Bar, and 14VDC. A conversion ratio of 1.035:1 can be used for gasoline flow rates. Grease is supplied for lubricating o-rings prior to installation.","brand":"Racetronix","offers":[{"title":"Default Title","offer_id":52663409836344,"sku":"FJ-SM-12S","price":50.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687141684.jpg?v=1784326680","url":"https:\/\/store.motormia.co\/products\/42-lb-hr-disc-high-z-fuel-injector","provider":"MOTORMIA","version":"1.0","type":"link"}
