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 will gradually reduce engine power and increase fuel consumption as the engine struggles to draw sufficient air. If left unreplaced, it can lead to excessive soot buildup in the combustion chamber and potential engine damage. Continued operation with a severely restricted air filter can cause engine overheating.

Installation Tip

Before installing the new filter, thoroughly clean the air filter housing to prevent any debris from entering the intake system. Ensure the filter is seated correctly and the seal is tight to prevent air bypass.

Service Note

Inspect the air intake system, including hoses and clamps, for leaks or damage when replacing the air filter.
