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

An initial symptom of a failing air filter may be a noticeable decrease in engine power or a slight increase in exhaust smoke. If the filter becomes completely blocked, the engine will struggle to breathe, leading to significant performance loss and potentially causing damage to internal engine components. Continued operation with a clogged filter risks accelerated wear on cylinder walls and pistons.

Installation Tip

Before installing the new air filter, ensure the air cleaner housing is completely clean and free of any dust or debris. Make sure the new element seals properly to prevent unfiltered air from entering the engine.

Service Note

When replacing the air filter element, it is a good practice to inspect the turbocharger and intake piping for any signs of oil or carbon buildup.
