This Nostrum set flows 1000cc\/min - roughly 66% more than the stock WRX injector - using a twin spray, split gamma pattern with a bend angle developed for the EJ head and intake valves. They go in like a factory part: every seal is in the box and there are no adapters, rails or spacers to buy. The spray is side specific, so each injector is colour marked for its bank.\u003c\/p\u003e\u003ch2\u003eBest For\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eA VF-series turbo WRX or STI at injector duty cycle that cannot safely take more boost or timing.\u003c\/li\u003e\n\u003cli\u003eSwitching to E85 or an ethanol blend, which needs a big step up in injector volume for the same air.\u003c\/li\u003e\n\u003cli\u003eSorting the fuel side without cutting an aftermarket rail and spacer kit into the intake manifold.\u003c\/li\u003e\n\u003cli\u003eForester XT, Legacy GT and Saab 9-2X Aero builds, where a well-aimed EJ-specific injector is otherwise hard to find.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eGetting Past The Stock Injector On A Tuned EJ\u003c\/h2\u003e\u003cp\u003eNostrum quotes 1000cc\/min against the stock WRX injector, a 66% increase in flow capacity. On a modified EJ that is usually the difference between a tune the calibrator has to protect and one they can actually optimise, because there is finally injector left at the top of the rev range to run the fuel targets the boost demands. Against a generic large port injector the argument is aim rather than size: this one was designed for the EJ port, not adapted to it.\u003c\/p\u003e\u003ch2\u003eSide-Specific Spray And Why It Is Marked\u003c\/h2\u003e\u003cp\u003eMost aftermarket port injectors suit many engines, so the cone is a compromise nobody optimised for your head. Nostrum's twin arc pattern is aimed at the back of the EJ intake valves, and because the banks mirror each other the injectors are assigned to a side and colour marked. Fit them the wrong way round and you undo the reason for buying them.\u003c\/p\u003e\u003ch2\u003eKey Specs\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eManufacturer: Nostrum High Performance\u003c\/li\u003e\n\u003cli\u003eProduct type: port fuel injectors (PFI)\u003c\/li\u003e\n\u003cli\u003eSKU: L071-1272\u003c\/li\u003e\n\u003cli\u003eFlow rate: 1000cc\/min, 66% more than the stock WRX injector\u003c\/li\u003e\n\u003cli\u003eSpray: twin spray, split gamma, EJ-specific bend angle, side-specific cylinder assignment\u003c\/li\u003e\n\u003cli\u003eIncluded: all required seals, full-colour installation guide, tuning guide for your tuner\u003c\/li\u003e\n\u003cli\u003eNot required: adapters, aftermarket fuel rails or spacers\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFitment And Setup Checks\u003c\/h2\u003e\u003cp\u003eCheck your model and year below; several earlier cars need a top feed conversion first, which is a separate job.
