Installation & Application Notes

Never run an engine without a filter — even briefly causes abrasive damage. Pre-fill fuel filters with clean fuel before fitting to reduce prime time. Replace O-rings on filter housings every second service. Record change dates on filter housing.

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 initially manifest as a gradual reduction in engine power and potentially increased fuel consumption. If left unreplaced, it can lead to excessive soot buildup in the exhaust and premature wear on engine internals due to insufficient airflow.

Installation Tip

Before installing the new filter, thoroughly clean the air filter housing to remove any accumulated dirt or debris. Ensure the filter is seated correctly and the housing is sealed properly to prevent unfiltered air from bypassing the element.

Service Note

Inspect the intake manifold and turbocharger (if equipped) for any signs of oil or soot buildup when replacing the air filter.
