The Southbay Fuel Injectors (SFI) 1200cc injectors are a slightly bigger step up from the 1,000cc’s. These also run e85 fuel, and can support over 700whp (depending on your fuel and setup; fuel return ensures higher availability and thus, more power). These injectors maintain strict linearity (meaning exact straight-line flow, so there is no deviation) at flow rates that will satisfy idle and cruise requirements as well as perfect WOT demands, making these ideal for emissions-compliant OEM applications. These also offer the ability to attain high flow rates required for boosted motors. These high-impedence injectors fit K-series motors with no fuel rail spacers, no injector resistors, and include pigtails for an easy splice-in installation.And, like all SFI injectors, these come with their 3 year, NO QUESTIONS ASKED warranty! Sold in sets of 4. Made proudly in the USA.

Using the same Bosch injectors as ID, FIC, and other companies, these injectors have the same proven flow rates and dead times. SFI ensures the quality of their injectors, and all work is done in-house – so they guarantee all their work for 3 years – no questions asked. With a maximum pressure capability of 7 bar and excellent low pulsewidth extension, this is a versatile injector that will be ‘at home’ in many different applications. From high power, high boost daily drivers, to world record-setting setups, SFI has you covered!
