Bosch 0445120057 Common Rail Injector (0 445 120 057) | OEM Cross-Refs 2854608 / 504091505 For Case IH–New Holland & Iveco Applications

When a machine starts to feel "tired" but not broken-slower cranking, uneven idle, a puff of smoke on throttle, or a power dip that comes and goes-many buyers go straight to the turbo or the pump. In real workshop life, the culprit is often simpler: one injector has drifted out of balance. The Bosch 0445120057 (Bosch No. 0 445 120 057) is a common rail injector frequently matched to Case IH / New Holland (CNH) and Iveco OEM references, and it's one of those part numbers that shows up again and again in fleet purchasing because it solves a very specific business problem: restore consistent combustion without guesswork.

If your customer arrives with any of these, they are typically trying to land on the same injector:

Bosch: 0445120057 / 0 445 120 057

Bosch reman/exchange reference (commonly listed): 0986435552

OEM cross references commonly shown in catalogs: 2854608, 504091505, 504091505R, 500060544, 500061278

This "number map" matters on Google because many buyers search the OEM number first (e.g., 2854608 or 504091505) and only discover the Bosch number later.

 

Across diesel specialists and catalog-style listings, 0 445 120 057 / 0445120057 is consistently associated with CNH (Case IH / New Holland) and Iveco ecosystems.
Some retailers label it directly as a Case-New Holland fuel injector under the Bosch number.
You may also see it marketed under CNH engine-family wording like "Holland N67" in parts channels, which aligns with how many buyers identify their equipment rather than by VIN.

Fitment best practice: match 0445120057 / 0 445 120 057 first, then confirm your equipment OEM reference (2854608 / 504091505, etc.). "Fits" lists can be broad-part-number matching is safer.

 

Common rail is a control system, not a simple fuel delivery setup. The ECU expects each cylinder to respond predictably to tiny injection commands. When one injector drifts, the ECU compensates-and that compensation shows up as the annoying, expensive symptoms operators hate:

◆ harder starts (especially after sitting)
◆ rough idle / vibration
◆ smoke under load or on acceleration
◆ inconsistent pull and rising fuel use

Replacing with the correct Bosch injector restores cylinder-to-cylinder balance, which usually feels like the engine "wakes up" even though nothing else changed. That's why fleet buyers keep this part number on their radar: it reduces downtime and comebacks when the diagnosis points to injector imbalance.

 

 

Online results commonly show two purchasing paths:

🆕 New injector sold under 0 445 120 057 / 0445120057 (often "new boxed" phrasing)
♻️ Exchange/reman reference frequently listed as 0986435552 alongside the same OEM mappings (2854608 / 504091505 / 500060544 / 500061278).

For your independent site, clearly label whether your SKU is new or reman/exchange, and state the cross-refs up front-this is exactly what customers compare before they click "Buy."

 

Parts buyers often need quick confirmation that the listing matches their internal system. High-signal details commonly published by suppliers include the exact cross-reference bundle (Bosch + OEM numbers).
Many specialist listings also present it explicitly as a Bosch common rail injector with CNH/Iveco OEM references, which helps purchasing teams standardize ordering.
