Engineered for the demanding requirements of the CAT C12 platform, the 212-3464 fuel injector delivers OEM-equivalent performance across a broad spectrum of heavy-duty applications. Designed as an Electronic Unit Injector for the inline 6-cylinder, 11.9-liter turbocharged diesel engine with power ratings from 355HP to 505HP, this component is purpose-built for on-highway trucks, generator sets, marine propulsion, and industrial power units operating under continuous high-load conditions.

The injector integrates precision nozzle technology, hardened internal components, and advanced solenoid design to ensure consistent fuel metering and stable injection pressure throughout the service life. OEM flow calibration, high pressure resistance, and corrosion-resistant materials work together to improve combustion efficiency, increase engine power output, enhance throttle response, and reduce both fuel consumption and exhaust emissions. Every unit undergoes factory testing to validate leak integrity, spray pattern, and dynamic flow performance prior to shipment.

Compatible with Freightliner, Peterbilt, Kenworth, and International truck platforms, as well as Caterpillar construction, mining, agricultural, and energy-generation equipment, the 212-3464 injector is backed by a 12-month typical warranty. Correct seating bore preparation, replacement of seals and O-rings, adherence to Caterpillar torque specifications, and post-installation leak and performance verification are recommended to maximize service life and protect downstream engine components.
