Engineered for Caterpillar's proven 3500 Series heavy-duty diesel engines, the 6I-4357 Fuel Injector Assembly is a high-precision diesel injection component serving the 3508, 3512, 3512A, 3512B, and 3516 engine models. Acting as the final precision component in the diesel fuel delivery system, it delivers accurate fuel metering and optimized atomization under high-pressure operating conditions. This precision injection performance directly supports maximum engine efficiency, stable power output, improved fuel economy, lower smoke emissions, better cold starting, and long-term operational reliability.

The 6I-4357 (alternative number 6I4357) is cross-referenced against OEM and remanufactured numbers 0R-1759, 7W-2269, 7C-9576, 0R-2781, and 712943AT, simplifying sourcing for distributors, remanufacturing centers, and diesel injection specialists. The injector is extensively deployed in power generation systems, marine propulsion and auxiliary engines, oil and gas equipment, mining machinery, construction equipment, industrial power plants, data center backup generators, offshore power modules, and continuous prime power stations across global markets.

Supplied in brand-new condition with a remanufactured version also available, the injector provides OEM-level performance and fitment to help reduce downtime and maintenance cost while extending service life. Every unit is backed by a 12-month warranty, with neutral, OEM, or customized packaging options and global shipping available. For sustained performance, use ISO-standard diesel fuel, keep water out of the fuel system, replace fuel filters on schedule, and conduct periodic injector testing such as bench, leak-off, and cylinder balance tests.
