Siemens injector well-suited for 8v 4cyl & Mk2/3 VR6 engines. Proven functional but not ideal for multivalve engines. Features narrow-angle single cone, decent response, and minimal atomization at injector nozzle (but more upon impact with hot intake valves). Fuel rail spacers required for 1.8T 20v engines other than AEB/AGU. Especially for multivalve applications, Genesis II 1000cc are a far superior choice.
