0432191730 Bosch Fuel Injector Set of 6 for Volvo FL10 F10 NL10 Volvo Penta TWD1030/1031 Engines

Complete set of 6 genuine new Bosch 0432191730 diesel fuel injectors (mechanical nozzle-and-holder assemblies, Bosch DHK family) — a full engine set for the 6-cylinder Volvo TD103 truck engines (F10, FL10, NL10), the Volvo BM TD103K construction-equipment engines, and the Volvo Penta TWD1030 ME marine and TWD1031 E industrial engines. Replacing all 6 injectors as a matched set restores balanced fuel delivery across all cylinders — the recommended practice for high-hour diesel engines.

Each injector is a complete mechanical nozzle-and-holder assembly with a factory-set opening pressure of 260–268 bar, supplied brand-new in its original individual Bosch box. Always confirm compatibility by Bosch number, OE number, engine code, engine serial number, or the identification number stamped on the original injector before ordering.

Also Available Individually

Need fewer than 6? This injector is also sold per piece — see the single Bosch 0432191730 injector listing. Buying the complete set saves 34 EUR versus 6 individual pieces.

Why Replace Injectors as a Complete Set

On a high-hour diesel engine, all 6 injectors wear at a similar rate. Replacing only one injector leaves 5 worn units in service, producing uneven cylinder balance, smoke and vibration, and usually leads to repeat downtime shortly after. A matched set of 6 new injectors restores identical opening pressure and spray pattern on every cylinder in a single intervention — one workshop visit, one set of seals, one calibration baseline.

Opening pressure	260 – 268 bar (factory set)

FAQ

How many injectors are included? Six brand-new genuine Bosch 0432191730 injectors, each in its original individual Bosch box — a complete set for one 6-cylinder engine.

Are these genuine Bosch fuel injectors? Yes. All six are brand-new genuine Bosch OEM diesel fuel injectors supplied in original Bosch packaging, made in Brazil.

Which engines use Bosch 0432191730? The Volvo TD103 truck engines (F10, FL10, NL10), the Volvo BM TD103 KAE/KBE/KCE construction-equipment engines, and the Volvo Penta TWD1030 ME marine and TWD1031 E industrial engines.

Is this set used in marine engines? Yes. It is the OEM injector (Volvo Penta 479443) for the Volvo Penta TWD 1030 ME commercial marine propulsion engine, per the official Bosch / Volvo Penta application guide.

Can I buy a single injector instead? Yes — the same injector is available per piece here. The set price saves 34 EUR versus 6 single pieces.

What is the opening pressure? Each injector has a factory-set opening pressure of 260 to 268 bar.

Are these common rail injectors? No. These are mechanical nozzle-and-holder assemblies (Bosch DHK family), not common rail injectors.

Are nozzle sealing washers included? No. Sealing washers are NOT included and must be sourced separately or reused per engine specification — fitting new washers is recommended when installing a full set.

Why replace all 6 injectors at once? A matched set restores identical opening pressure and spray pattern on all cylinders, avoiding the uneven running and repeat downtime that follow single-injector replacement on a worn engine.

Is professional installation recommended? Yes. Professional installation is recommended to ensure correct fitment and proper torque settings.

Diagnostic Information

Common Symptoms of Fuel Injector Failure

Hard starting, long cranking, unstable idle, engine misfiring, loss of power, rough running, excessive smoke, knocking, or increased fuel consumption may indicate worn or faulty injectors. These symptoms can also be caused by the injection pump, fuel filtration, air in the fuel system, low compression, or other diesel engine management issues, so a full diagnosis is recommended before replacement.

Installation and System Check

Before replacing diesel fuel injectors, inspect the fuel filter, check for water or contamination in the fuel, and verify injection pump operation. Installing new injectors into a contaminated fuel system may result in repeat failure. When fitting a complete set, replace the fuel filter and use new nozzle sealing washers on every cylinder.
