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 dirty air filter will initially cause a reduction in engine power and potentially increase fuel consumption. If not replaced, it can lead to increased soot buildup in the exhaust and accelerated wear on engine cylinders and rings. Severe restriction can cause engine misfires and difficulty maintaining idle speed.

Installation Tip

Ensure the air cleaner housing is clean and the sealing surfaces are free of debris before installing the new element. Make sure the element is seated correctly to create a proper seal.

Service Note

Inspect the air intake system, including hoses and clamps, for any leaks or damage that could allow unfiltered air into the engine.
