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

An initial symptom of a failing air filter assembly can be a gradual reduction in engine power and responsiveness. If the issue persists, it may lead to increased fuel consumption and visible black exhaust smoke. The ultimate risk is accelerated internal engine wear and potential damage to pistons and cylinder walls from ingested contaminants.

Installation Tip

Always clean the mounting surface and ensure all seals are properly seated before tightening the assembly to prevent air leaks. Never operate the engine without the air filter element installed, even for a short period.

Service Note

Inspect the pre-cleaner (if equipped) and clean or replace the intake hoses and clamps as needed.
