Specifically designed injectors that directs fuel to the valve bevels to match the port shape of the VR38.
While standard high-capacity injectors have one jet, which hits the wall surface of the port junction directly. This product has two jets that matches the port geometry. The 14-hole layout allows for angled injection, allowing fuel to be directed between the valve stem and port wall towards the valve bevel.
Stabilizes combustion by preventing fuel from adhering to walls and reduces fuel flow into the combustion chamber in a liquid state.
The stock connector shape eliminates the need for modification. 
Designed to match the static flow rate of one unit in the range of ±1%.
 
Improving the tuning level such as upgrading the turbine usually requires replacing injectors with larger capacity injectors.
A set of large-capacity injectors for one vehicle.

2-Jet TYPE INJECTOR UPGRADE
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.
