Hong Nor #356A - Air Filter Foam

The Hong Nor #356A Air Filter Foam (part HN#356A) is a replacement foam element for RC air filter assemblies, helping to keep dust and debris away from your engine for consistent running and protection.

Ideal for routine maintenance, replace worn or contaminated foam to maintain reliable airflow and filtration. Confirm the part number matches your specific air filter housing before installation.

Care And Use

• Inspect the foam regularly and replace if torn, compressed, or heavily soiled.
• Apply suitable air filter oil if your setup requires it, then squeeze out excess to balance filtration and airflow.
• Allow any applied oil to settle before use.
