DEUTZ 0425-3964KZ Turbocharger

DEUTZ 0425-3964KZ Turbocharger is an OEM-style forced-induction component designed for Deutz BF4M1013-series diesel engines, delivering boosted intake air to improve combustion efficiency and engine power during heavy loading. This S2A-class unit (BorgWarner-derived 314280) is commonly used on Deutz BF4M1013-powered trucks produced in the 1990s and 2000s, with OE references including 04253964KZ, 04205625KZ, and 04205630KZ indicating interchangeability across BF4M1013/B4FM1013 installations. The 0425-3964KZ designation appears in catalogs as a replacement for Deutz BF4M1013 engines and is tied to the 314280 S2A variant. Typical applications cover Deutz truck engines from roughly 1993 through 2010, though exact fit depends on the engine variant and mounting hardware. In operation, the turbocharger uses exhaust-gas energy to spin a turbine that compresses intake air, feeding a higher-velocity charge to the cylinders and enabling higher torque and sustained performance under load when paired with the correct intercooling and exhaust plumbing.
