2. Injection Molding: Japan Sumitomo 3500T precision molding (±1°C mold temp control)

3. Post-Processing: CNC trimming + ultrasonic flaw detection

4. Quality Control:

   • First-article CMM inspection

   • Hourly hardness checks (Shore D78±2)

   • 100% AI visual inspection

4. Important Notes

 Installation Warnings

• Must replace timing chain tensioner simultaneously (recommended kit purchase)

• Requires ECU adaptation reset via ISTA system post-installation

Usage Tips

• Allow 15-minute idle run after first startup for break-in

• Recommend inspection every 50,000 km for wear
