This is a set of six intake valves for a CAT engine, essential for controlling the admission of air-fuel mixture into the combustion chambers. Manufactured to meet strict OEM material and dimensional specifications, these valves offer superior heat resistance and sealing compared to worn or damaged valves. Operators may notice a loss of engine power, rough idling, increased exhaust smoke, or a decrease in fuel efficiency when these intake valves are not sealing properly or are damaged.
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.
A rough or uneven engine idle, accompanied by a noticeable reduction in engine power, are common initial symptoms of faulty intake valves. If the issue progresses, the engine may begin to misfire, exhaust smoke may increase, and fuel economy will decline. Continued operation with compromised intake valves can lead to increased wear on other engine components and potential cylinder head damage.
Ensure the valve seats are perfectly clean and free of debris before installing the new valves to guarantee a proper seal. Avoid dropping or bending the valve stems during handling and installation.
Inspect valve seats, valve guides, and piston rings for wear when replacing intake valves.
