Genesis 415cc injector fits small-port 20v heads and R32 directly. For 16v or big port 1.8T, just add a set of Unspacers and you're set. Features factory-correct dual spray cones, fast response, with atomization directly from injector nozzle and more upon impact with intake valves. Fuel rail spacers not required (except Audi 2003+ with dark blue injectors).
Because fuel is aimed directly at valves and wall-wetting is avoided, these injectors are exceptionally easy to tune with. Flow at 3bar pressure is perfect to support hp in the low 300s on pump gasoline. Up to 4.5bar fuel pressure setting recommended to generate significantly more. Parts are priced each.
