Bosch original 0414702010 Fuel Components Fuel Injector Diesel Engine FM Common Rail Nozzle for Large Truck Engine 21160093 0414702015 0414702014 original new injector

Engineered specifically for the Volvo D12 engine platform, the BOSCH 0414702021 PDE Unit Injector delivers precise fuel metering across the full D12A, D12C, and D12D power range. This injector is verified compatible with D12A340, D12A380, D12A420, D12C340, D12C380, D12C420, D12D420, and D12D460 configurations, ensuring accurate replacement for FH12, FM12, and NH12 vehicles as well as Volvo industrial, marine, and generator applications.

Built on Bosch OE engineering, this 702 Series unit integrates high-pressure fuel generation and injection into a single precision assembly using PDE technology. Each component features factory calibration, superior atomization, and corrosion-resistant construction for long service life under demanding operating conditions. The injector cross-references OE numbers 0414702010, 20381597, 20440409, 3155044, 8113408, 8170569, 6050251, and 5237322, simplifying fitment across heavy-duty transportation, power generation, construction, mining, and agricultural machinery.

To maximize durability, operate with ultra-clean diesel fuel, replace filters regularly, and avoid water contamination while monitoring rail pressure and injector return flow. Diagnostic support includes injector bench testing, return flow testing, leakage testing, ECU diagnostic scan, fuel pressure verification, and resistance measurement. Backed by consistent Bosch quality, this unit injector provides reliable, drop-in performance for professional fleet, marine, and industrial maintenance programs.
