This 0337 2161 nozzle holder is machined in-house for Deutz FL413 series air-cooled engines, including FL413FW and F8L413F variants commonly found in stationary gen-sets and older fleet equipment undergoing top-end overhaul[citation:1]. The holder’s injector bore is honed to a surface finish that matches the original clamping interface, preventing the carbon migration path that causes nozzle seizure in high-hour engines. Each production lot is dimensionally verified against a retained OEM sample, and units are packed with protective caps on both fuel inlet and nozzle seat faces for sea freight. For export orders, we support quantity breaks at 50-piece increments and can combine this item with FL413 cylinder head and gasket sets in a single consolidated shipment.
