HKS Fuel Upgrade Kit - Fuel Injectors & Pumps

Fuel Upgrade Kit 800cc for Subaru Impreza

Fuel upgrade parts for Subaru Impreza

Large capacity injector and fuel pump set that are required to increase horsepower.

* ECU resetting is required to change injector or fuel pressure.

● Application

• Injector (Top feed, high impedance, compatible with short (55mm)type)
  EJ207 GRB (blue)/GDB (pink)
  EJ255 BM,BR (green)/BL, BP (blue)
  EJ257 GRF (blue)
• Fuel pump
  GRB, GRF, GDB (BM, BR/BL, BP not tested)

● Performance

Capacity of stock injector of Impreza is for up to around 350PS.
(The same limitation as stock turbine.)
Supply volume from fuel pump will decrease at high boost level.
Therefore, upgrading of fuel parts is required to replace with a big turbine.

● Injector

■ Features (Concept)

• Enough capacity for a big turbine.
• With insulators on both ends of injector, no modification is required for installation.
• Injection direction towards intake valve.
  ⇒ As a result, response of air / fuel ratio will improve because of less volume of fuel for cylinder from surface of port.

Fuel parts are very important to achieve 'Big Power'. HKS offer a wide range of Fuel parts, including Pumps, Injectors, Upgrade Kits, Regulators and Delivery Kits. As performance levels increase via greater airflow efficiency or higher boost levels, fuel delivery is crucial in developing maximum horsepower and in maintaining proper air/fuel ratios.
