This is an air filter kit designed to remove particulate contaminants from the intake air before it enters the engine's combustion system. Manufactured to meet stringent filtration standards, it ensures clean airflow for optimal combustion and engine longevity, outperforming clogged or damaged filters. A clogged air filter can manifest as reduced engine power, increased fuel consumption, and black smoke from the exhaust.

Installation & Application Notes

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.

Failure Symptoms

A clogged air filter initially causes a gradual decrease in engine power and responsiveness, along with a slight increase in fuel consumption. If left unreplaced, severe restriction can lead to incomplete combustion, resulting in excessive black smoke and potential engine overheating. Continued operation with a severely restricted filter can lead to premature engine wear and reduced performance.

Installation Tip

Ensure the filter housing is completely clean before installing the new filters, paying close attention to the sealing surfaces. Do not operate the engine without the air filter installed, even for a short period.

Service Note

Inspect the intake manifold and turbocharger (if equipped) for oil or soot buildup when replacing the air filters.
