This is a set of four CAT fuel injectors, precisely engineered to deliver the correct amount of fuel into the engine cylinders for optimal combustion. Manufactured to meet exact specifications, these injectors ensure consistent fuel atomization and spray patterns superior to worn or clogged units. Operators may notice rough idling, reduced engine power, increased exhaust smoke, or difficulty starting if these injectors are not functioning correctly.
Always verify with serial number before ordering.

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
The initial symptom of failing fuel injectors is often a rough or uneven engine idle, accompanied by a noticeable loss of power. As the condition worsens, increased exhaust smoke (black or white) and higher fuel consumption may become apparent, potentially leading to engine misfires. Continued operation with faulty injectors can result in incomplete combustion, potentially damaging the engine and emission control systems.
Ensure the injector seats and fuel lines are meticulously clean before installation to prevent fuel leaks or contamination. Avoid overtightening the injector hold-down bolts, as this can damage the injector body or cylinder head.
Inspect the fuel filter, fuel lines, and engine control module for any related issues when replacing fuel injectors.
