{"product_id":"disc-high-z-fuel-injector","title":"Disc High-Z Fuel Injector","description":"The Racetronix FJ-SM-51S is a high-impedance fuel injector designed for high-performance aftermarket applications. It features a disc design that resists build-up and clogging, ensuring a longer service life and consistent fuel flow. The high-speed disc action provides a wider dynamic flow range, contributing to improved idling and quieter operation. Its flat mating surface prevents excess fuel evaporation and deposits.\n\nDynamically flowed and grouped to within 1% tolerance when purchased in packs, these injectors utilize Racetronix's custom flow bench. Testing is conducted with n-Heptane at specific pressures and voltages, with results convertible to gasoline flow rates using a 1.035:1 ratio. This high-impedance injector is compatible with all factory ECM\/PCM injector drivers. Grease is supplied to lubricate the o-rings prior to installation for a proper seal and to prevent fuel leakage, aiding in quicker starts.\n\nWhile injectors sold individually (EACH) adhere to the listed factory tolerance, Racetronix offers flow-matched 1% injectors when purchased in packs via the 'Buy In' drop-down menu, ensuring optimal performance and consistency for demanding applications.","brand":"Racetronix","offers":[{"title":"Default Title","offer_id":52663410000184,"sku":"FJ-SM-51S","price":50.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687141688.jpg?v=1784326683","url":"https:\/\/store.motormia.co\/products\/disc-high-z-fuel-injector","provider":"MOTORMIA","version":"1.0","type":"link"}
