{"product":{"id":11142672941398,"title":"Nostrum BMW S63 4.4 V8 High Flow DI Injectors (Set Of 8)","body_html":"\u003ch2\u003eSummary\u003c\/h2\u003e\u003cp\u003eThe S63 is BMW's 4.4 twin-turbo V8, and once it is tuned hard or fed ethanol the factory direct injectors become the restriction. Nostrum's high flow set replaces all eight with injectors flowing 20.2 g\/s at 100 bar and rated to 250 bar of operating pressure. How big a step that is depends on which S63 you have: it is 31% more than the EU5 S63TU injector and 59% more than the EU6 S63TU2 part. Every injector is tested statically and dynamically, keeps an OEM-comparable spray pattern, and arrives with its decoupling ring already fitted, so the set drops in without a harness change or spacers.\u003c\/p\u003e\u003ch2\u003eBest For\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eF10 M5, M6, X5 M and X6 M builds on an aggressive map where injector duty is already at the limit.\u003c\/li\u003e\n\u003cli\u003eCars moving to E85 or ethanol blends, where a V8's fuel demand climbs fastest.\u003c\/li\u003e\n\u003cli\u003eUpgraded turbo S63 setups that need matched fuelling across all eight cylinders.\u003c\/li\u003e\n\u003cli\u003eOwners who want to keep the factory-style spray pattern rather than accept a compromised idle from a generic big injector.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTwo Different Stock Injectors, Two Different Steps\u003c\/h2\u003e\u003cp\u003eThis matters when you are working out whether the upgrade is worth it. An earlier EU5 S63TU car gains 31%, because its factory injector was already fairly large. A later EU6 S63TU2 car gains 59% from the same part. Same injector, very different headroom, so identify which engine variant your car left the factory with before you plan the tune around it. Nostrum quotes 1300 whp on petrol and 975 whp on E85 as what this injector can support in a fully built and calibrated car, not as a result of fitting it.\u003c\/p\u003e\u003ch2\u003eKey Specs\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eManufacturer: Nostrum High Performance\u003c\/li\u003e\n\u003cli\u003eProduct Type: high flow direct injectors, set of eight\u003c\/li\u003e\n\u003cli\u003eSKU: H750-1611\u003c\/li\u003e\n\u003cli\u003eVehicle Application: BMW S63 4.4 twin-turbo V8\u003c\/li\u003e\n\u003cli\u003eFlow: 20.2 g\/s at 100 bar\u003c\/li\u003e\n\u003cli\u003eFlow capacity: 31% over stock S63TU (EU5), 59% over S63TU2 (EU6)\u003c\/li\u003e\n\u003cli\u003eFitment type: direct fit, no harness or spacers needed\u003c\/li\u003e\n\u003cli\u003eIncluded: eight injectors with OEM decoupling rings pre-installed, installation instructions\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFitment And Setup Checks\u003c\/h2\u003e\u003cp\u003eConfirm the model year against the table below, then confirm the engine variant, since EU5 and EU6 cars start from different factory injectors.
