HKS original 2-Jet type Injector Upgrades were designed specifically for certain engines; therefore, installation is very simple. For higher combustion efficiency, this injector was designed to inject fuel toward the valve head with better fuel atomization.
Injection toward Valve Head
Injection direction was carefully adjusted toward the valve head; therefore, the A/F response delay due to inefficient injection can be improved.
Better Fuel Atomization
As the injection range gets wider, the atomized particle size becomes smaller; therefore, combustion efficiency can be improved with less black smoke. Also, the fuel atomization improvement can lead better low-temperature startability and A/F response which improve the torque.
