Description

HPI Diesel Unit Injector 1521978 Cross OE 4088725 4902818 574398 For Cum-mins ISX15 QSX15 Scania DT12 Heavy Truck Engine Fuel Injector

1464994 is premium HPI electronic unit injector (EUI), OEM direct replacement matching cross OE numbers 4088725, 4902818, 574398, 1764364, 4076912. It perfectly fits cum-mins ISX15, QSX15, X15 engines and Scania DT12.02 / DT12.06 / DT12.18 heavy-duty engines, widely installed on Scania P/G/R/T series long-haul tractors, dump trucks and engineering vehicles, fully compliant with Euro 4 & Euro 5 emission standards for heavy commercial vehicles.
This integrated HPI EUI injector adopts wear-resistant multi-hole alloy nozzle and built-in high-speed electromagnetic control valve, supporting pilot + main multi-stage split injection under ultra-high pressure. It effectively fixes typical engine malfunctions: insufficient power, thick black smoke, hard cold startup, unstable rough idle, over-high fuel consumption, internal fuel leakage, cylinder misfire and abnormal vibration under full-load long-distance transportation.
The injector body is forged from high-strength anti-corrosion alloy steel, equipped with imported FKM high-temperature sealing rings and color-coded multi-layer gaskets, resisting continuous high working temperature, heavy load and intense mechanical vibration of heavy trucks. Every finished injector undergoes full-flow professional bench calibration for injection timing, fuel delivery balance, atomization uniformity and tightness leakage test before shipment.
Installation Reminder: ECU coding matching is required after replacement; core deposit policy applies for remanufactured injectors.
We supply brand new and remanufactured injectors in stock, neutral export carton packaging, customizable customer logo packing, flexible MOQ and tiered bulk wholesale discounts. Our 12-month global warranty provides reliable after-sales support for worldwide heavy truck spare parts distributors, truck repair workshops and logistics fleet maintenance yards.
