What you are ordering
Price is per fuel injector, and all part numbers are separate variants — choose the correct part number you need from the variant menu. These injectors are not interchangeable, different part numbers correspond to different fuel flow rates and power settings. Fitting the wrong injector will lead to abnormal fuel consumption, smoke output and engine power deviation.

Specifications
Material: high-strength alloy steel, precision machining of internal passages
Construction: PT STC structure, pressure calibrated
Flow rate and timing: to standard specification
Finish: anti-corrosion and wear-resistant treatment, each unit tested before packing
Packing: individually protected, part number labelled on the bag

When to replace
Fuel injectors wear from contaminated fuel, poor filtration and long running hours. Typical symptoms are black or white exhaust smoke, rough idle, cylinder misfire, high fuel consumption, loss of power and overheating. If the injector is clogged, leaking or poorly atomizing, replace it promptly and inspect the fuel filter and fuel tank for contamination.

Fitting notes
Clean the injector bore and fuel passages thoroughly before installation. Torque the injector according to the K19 service manual, then perform fuel timing check after replacement. If you are unsure which injector matches your engine CPL, send us your engine serial number and we will confirm the correct part number.
