On a B8 S4 or S5 running a pulley and a map, the injector is often the part quietly capping the calibration, and 15% extra volume is the difference between a tuner working around the fuelling and working with it. These flow 1484 cc\/min at 100 bar with a 180 bar maximum operating pressure and an OEM compatible spray pattern, and they went through seven months of in-vehicle testing before release. They drop straight in as a Bosch HDEV5 replacement with no harness and no spacers, and all the factory diagnostic functions carry on working as they did.\u003c\/p\u003e\u003ch2\u003eBest For\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eB8 S4 and S5 cars on a pulley and map where the injector is the fuelling limit\u003c\/li\u003e\n\u003cli\u003eSQ5, Q5, Q7, A6 and A7 owners keeping a factory-behaving fuel system\u003c\/li\u003e\n\u003cli\u003eEthanol blends on the supercharged V6, where volume demand rises\u003c\/li\u003e\n\u003cli\u003eA straight swap with no wiring changes or spacer work in the way\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhy 15% Is The Right Size Step Here\u003c\/h2\u003e\u003cp\u003eThis is not a race-injector jump, and that is deliberate. A modest, well-matched increase keeps the minimum pulse width behaviour close to standard, which is what keeps idle and part-throttle drivability clean while giving the tuner room at the top. The factory injectors are Continental; these are built on the Bosch HDEV5 family and swap in the same place.\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 injection (DI) injector set\u003c\/li\u003e\n\u003cli\u003eSKU: H720-2023\u003c\/li\u003e\n\u003cli\u003eVehicle Application: Audi EA837 3.0 TFSI supercharged V6, CAJA and CCAA\u003c\/li\u003e\n\u003cli\u003eFlow: 1484 cc\/min at 100 bar, 15% larger than stock\u003c\/li\u003e\n\u003cli\u003eMax operating pressure: 180 bar \/ 18 MPa \/ 2610 psi\u003c\/li\u003e\n\u003cli\u003eSpray pattern: OEM compatible\u003c\/li\u003e\n\u003cli\u003eFitment type: direct replacement, no harness or spacers required\u003c\/li\u003e\n\u003cli\u003eFuel compatibility: ethanol compatible\u003c\/li\u003e\n\u003cli\u003eIncluded items: injector set with installation guide; tuning data available through dealers and tuners\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003ePump Or Injectors First On An S4 Or S5\u003c\/h2\u003e\u003cp\u003eMost supercharged V6 builds run into the injector first on a pulley and map, and the pump becomes the limit as the target climbs or the fuel changes.
