⚙️ Manufacturing Process of the Air Filter Complete Kit

1. Material Selection

   • High-quality, open-cell polyurethane foam is chosen for its filtration performance and reusability.

   • Reinforced steel or plastic cages are selected for strength and structural support.

2. Foam Cutting & Shaping

   • Foam sheets are precisely cut and formed into cylindrical or cone-shaped filters to fit OEM airbox specifications.

   • In multi-stage filters, a coarse outer layer is combined with a finer inner layer for dual-stage filtration.

3. Support Cage Fabrication

   • Inner cages are molded or stamped from steel or injection-molded plastic.

   • Designed to maintain filter shape under suction pressure and ensure even airflow.

4. Assembly

   • Foam is bonded to end caps and support cages using high-strength, heat-resistant adhesive.

   • Some filters are pre-oiled using a specially formulated sticky oil to trap microscopic dust particles.

5. Quality Control

   • Each unit is inspected for material defects, proper bonding, and fitment.

   • Airflow and filtration efficiency may be tested in controlled environments for performance validation.

6. Packaging

   • Assembled kits are packaged with instructions and labeled for specific model years (1987–2004 Yamaha Warrior 350 YFM350X).
