Dual Hose Air Assist Injectors were used primarily in Mitsubishi, Dodge, Chrysler, and some Nissan vehicles in the 1990s and early 2000s. These injectors were designed to improve fuel atomization and efficiency by using an additional air line along with the fuel line. These injectors were part of Mitsubishi’s Cyclone and Electronically Controlled Multipoint Fuel Injection (ECFI) systems, which improved atomization and combustion efficiency by introducing air into the fuel stream.

How These Injectors Work
- These dual-hose injectors use a separate air line to introduce pressurized air into the fuel stream before injection.
- The air assist system was mainly for improving fuel atomization, reducing emissions, and enhancing cold-start performance.
- Found in vehicles with electronically controlled multipoint fuel injection (ECFI).
