Product Specifications:
Engineered to conquer the freezing temperatures and grueling payload demands of heavy-duty commercial transport and industrial machinery, the 0445120178 is a rugged aftermarket Common Rail Diesel Fuel Injector. Specifically calibrated for the highly resilient YaMZ 534 and 536 commercial diesel engines, this precision component seamlessly restores factory-level fuel atomization and rail pressure stability in the most extreme working environments.
-
Restores Massive Towing Capacity: Cures sluggish throttle response and brings back the essential low-end pulling power required for fully loaded commercial trucks and passenger buses to maintain strict transit schedules across challenging terrains.
-
Eliminates Thick Black Smoke: Instantly resolves rough engine idling and excessive unburnt fuel issues, protecting your fleet’s exhaust aftertreatment system from costly DPF soot accumulation and unnecessary downtime.
-
True Plug & Play Installation: Manufactured as a direct mechanical drop-in, this high-precision unit requires absolutely zero complex ECU coding, getting your transport vehicles back on the road instantly.

👨🔧 Tech Notes & Installation Guide
-
💰 Why Replace the Full Set?
-
The Risk: Leaving an aging or degraded injector in a hard-working YaMZ commercial engine block creates massive fuel pressure drops. This directly results in violent cabin vibrations under heavy cargo payloads, significantly worse fuel economy, and a highly dangerous loss of pulling power during steep highway climbs.
-
The Fix: We strongly advise leveraging our Volume Discounts to install a completely synchronized set of 4 or 6 units (depending on your specific 534/536 engine block). This ensures perfectly balanced cylinder firing, returning your transport vehicle to a whisper-quiet idle and recovering its maximum factory hauling capacity.

-
✅ Direct Replacement (No Coding Required):
-
Rigorously flow-tested on advanced DCI calibration benches, this unit delivers true plug-and-play functionality. It requires absolutely zero IMA programming, bypassing expensive dealership diagnostic tools and slashing your fleet mechanic’s labor downtime.
-
-
⚠️ Critical Cleaning Step:
-
Commercial fleet fuel tanks inevitably accumulate heavy sludge and metallic micro-debris over thousands of miles. Failure to thoroughly flush the entire high-pressure fuel rail and install a brand-new OE-quality 5-micron fuel filter will cause instant contamination damage and strictly void the 30-day manufacturing defect policy.
