{"product":{"id":11142673662294,"title":"Nostrum Ford Fiesta ST 1.6 EcoBoost High Flow DI Injectors, Set of 4","body_html":"\u003ch2\u003eSummary\u003c\/h2\u003e\u003cp\u003eOnce a Fiesta ST has a bigger pump and a decent ethanol tune, the injector becomes the next thing to run short of time, and that is usually where talk turns to methanol kits and port injection. This set of four Nostrum high flow direct injectors keeps the answer inside the standard fuel system. Each flows 1211 cc\/min at 100 bar, a mass flow of 14.6 g\/s, 60 percent more than the factory 1.6 EcoBoost injector and 18 percent more than the JLR swap people have leaned on for years. They drop into the standard bores as a direct-fit replacement, carry a double Teflon combustion seal and run to 240 bar. The result is a car that will take full pump E85 and hold fuelling at the top end with nothing extra bolted to the boot floor.\u003c\/p\u003e\u003ch2\u003eBest For\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eFiesta STs on an upgraded pump that have hit an injector ceiling up top.\u003c\/li\u003e\n\u003cli\u003eDaily drivers where a methanol tank, pump and nozzle is not welcome.\u003c\/li\u003e\n\u003cli\u003eCars moving off a fixed blend onto whatever E85 the pump gives that week.\u003c\/li\u003e\n\u003cli\u003eBig-turbo 1.6 builds needing the fuel side sorted before the airflow side.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhy Spray Quality Matters As Much As Size\u003c\/h2\u003e\u003cp\u003eA larger injector is not automatically a better one. Get the plume wrong and you inherit poor idle, awkward drivability, more knock, soot and fuel washing down the bore into the oil. Nostrum develops these on spray patternation and arc flash equipment to hold an OEM-quality pattern at the higher flow, which is why they behave on a cold morning as well as on a timed run.\u003c\/p\u003e\u003ch2\u003eKey Specs\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eManufacturer: Nostrum High Performance\u003c\/li\u003e\n\u003cli\u003eProduct Type: Direct injection injector set, four injectors\u003c\/li\u003e\n\u003cli\u003eSKU: H720-1806\u003c\/li\u003e\n\u003cli\u003eVehicle Application: Ford Fiesta ST 1.6 EcoBoost, 2014-2019\u003c\/li\u003e\n\u003cli\u003eFlow: 1211 cc\/min at 100 bar, 14.6 g\/s, 60 percent over stock\u003c\/li\u003e\n\u003cli\u003eIncluded Items: four injectors with double Teflon seals and detailed fitting instructions\u003c\/li\u003e\n\u003cli\u003eRequired separately: supporting calibration; matching high pressure fuel pump for the full benefit\u003c\/li\u003e\n\u003cli\u003eFitment type: vehicle-specific, direct replacement for the standard injector\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFitment And Setup Checks\u003c\/h2\u003e\u003cp\u003eThese suit the 2014-2019 Ford Fiesta ST 1.6 EcoBoost. A tune is required and Nostrum lists COBB, with PHUL Performance, Dizzy Tuning, Livernois, Stratified and Tunewerks among its named tuners. The 240 bar ceiling is held back by the factory rail pressure sensor, so a sensor upgrade is needed to reach it. Injectors alone will not fix a pump-limited car, so if rail pressure already drops in the midrange, plan the pump into the same job. If you are unsure, use a professional fitter.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eManufacturer\u003c\/td\u003e\n\u003ctd\u003eNostrum High Performance\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eHigh flow direct injectors, set of four\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSKU\u003c\/td\u003e\n\u003ctd\u003eH720-1806\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVolume flow rate\u003c\/td\u003e\n\u003ctd\u003e1211 cc\/min at 100 bar, nHeptane\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMass flow rate\u003c\/td\u003e\n\u003ctd\u003e14.6 g\/s at 100 bar, Viscor 16A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFlow increase over stock\u003c\/td\u003e\n\u003ctd\u003e60 percent\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFlow increase over JLR injectors\u003c\/td\u003e\n\u003ctd\u003e18 percent\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum pressure\u003c\/td\u003e\n\u003ctd\u003e240 bar \/ 24 MPa \/ 3500 psi, limited by the OEM rail pressure sensor\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSealing\u003c\/td\u003e\n\u003ctd\u003eDouble Teflon combustion seal\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFuel\u003c\/td\u003e\n\u003ctd\u003ePetrol and full E85\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFuel system capacity\u003c\/td\u003e\n\u003ctd\u003e540 whp petrol, 440 whp E85, with a supporting build and tune\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTune required\u003c\/td\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWarranty\u003c\/td\u003e\n\u003ctd\u003eNostrum limited lifetime\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eVehicle Fitment\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eYears\u003c\/td\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eEngine\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2014-2019\u003c\/td\u003e\n\u003ctd\u003eFord Fiesta ST\u003c\/td\u003e\n\u003ctd\u003e1.6 EcoBoost\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\u003ch3\u003eDo these replace the need for methanol or port injection?\u003c\/h3\u003e\u003cp\u003eThat is exactly what Nostrum designed them for.
