The A-04-029-00-00 is a common rail diesel injector with electro-hydraulic needle control, metering fuel at injection pressures around 1600 bar across all engine operating modes. Common rail injection is the architecture of every modern diesel: a high-pressure rail feeds injectors that the engine controller fires electronically, and the injector itself — dosing fuel in milligram precision several times per combustion cycle — is the system's hardest-working precision component.
That work profile makes injectors a leading aftermarket category: they wear with fuel quality and hours, and every diesel in service eventually consumes replacements, with fuel-system parts ranking among the highest-value recurring positions in diesel maintenance. Electro-hydraulic needle control is the established serial technology, compatible with the service equipment and test benches of any diesel fuel-system workshop.
At $90 with a minimum order of 20, the injector addresses diesel-parts distributors, fuel-system repair specialists and fleet workshops. For importers, injectors are dense value — high price per kilogram, continuous demand tied to fleet hours, and a customer base of professional workshops that reorder on consumption.
