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

A clogged air filter initially causes a noticeable reduction in engine power and responsiveness. If ignored, the engine may start to run rough, produce black exhaust smoke, and consume more fuel. Continued operation with a severely restricted filter can lead to premature engine wear and potential internal damage.

Installation Tip

Ensure the air filter housing is thoroughly cleaned before installing the new filters to prevent any existing dirt from being drawn into the engine. Do not operate the engine without the air filter elements installed.

Service Note

Inspect the air intake piping and turbocharger for any signs of damage or oil contamination while replacing the air filters.
