1318822 Filter Element As-Air — Cat 120G 120H

This air filter element is crucial for removing particulate matter from the air drawn into the engine. It maintains optimal engine performance by ensuring a clean air supply for combustion and protecting sensitive internal parts from abrasive wear. A clogged filter will cause a noticeable drop in engine power and may lead to increased exhaust emissions.

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 gradual decrease in engine power and a tendency for the engine to stall under load are early indicators of a restricted air filter. If left unaddressed, the engine will consume more fuel and may experience increased internal wear. The ultimate risk is significant damage to engine components due to insufficient airflow and increased particulate ingestion.

Installation Tip

Ensure the sealing surfaces on both the filter and the air cleaner housing are clean and free of debris before installation. Do not overtighten the housing clamps, as this can damage the filter seal.

Service Note

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