Caterpillar original For Caterpillar C11 C13 Fuel Injector 292-3666 for Construction Machinery, Replacement for OEM 20R-8046, Cross Reference 253-0608, 249-0713 original new injector

Precision-engineered exclusively for Caterpillar C13 ACERT engine platforms, the 292-3666 diesel fuel injector is a mission-critical component for heavy-duty diesel power systems. Built to meet OEM performance specifications, it is compatible with all listed C13 variants including industrial, on-highway truck, marine, and generator engine models. It serves a wide range of equipment across transportation, construction, mining, marine, and power generation sectors, delivering reliable performance even under the most demanding operating conditions.

Controlled by the engine’s ECM to adjust injection timing with high precision, the injector atomizes diesel fuel into fine particles for optimized combustion, which translates to improved fuel economy, higher power output, faster engine response, and reduced exhaust emissions and particulate matter. Manufactured under strict industrial quality standards, it features stable high-pressure fuel delivery, corrosion resistance, heavy-duty durability, and a long service life in high-pressure operating environments.

The injector is available in new or remanufactured condition with an OEM-equivalent quality standard, and comes with a 12-month supplier-dependent warranty. With a minimum order quantity of 1 piece and available OEM services, it supports flexible B2B procurement. Proper installation requires adherence to Caterpillar torque specifications and post-installation diagnostic checks, while regular filter replacement and fuel quality monitoring align with official service guidelines to support long-term reliable operation.
