HKS Fuel Upgrade Kit - Fuel Injectors & Pumps

Fuel Upgrade Kit for MITSUBISHI LANCER EVOLUTION 7-9.
Large size injectors and a fuel pump, which are required for upgraded turbine, are in a set.

Limitation of stock injector of LANCER EVOLUTION VII - IX is about 380ps. (The same limitation as stock turbine). At high boost level (= high fuel pressure), electricity consumption of fuel pump is increased and drive voltage of pump drops and fuel supply volume also decreases. It causes fuel lean problem. Therefore, when turbocharger is upgraded, fuel system must be upgraded.

Injector

• It supplies enough fuel volume for upgraded turbine (Up to about 500ps).
• The injection direction is set to target intake valves. It improves response of Air/Fuel ratio.
• The injection hole is 2 holes type. The taper shape of holes improve mixture condition.

Fuel pump

• The same dimension as stock pump. It enables large supply volume with In-tank system.
  (Included extension adapter is used for installation.)
• The low electricity consumption prevents voltage drop of pump drive at high load. It also prevents increasing of fuel temperature.

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.
