Installation Guide – Thread Mismatch & Cross-Contamination

Installation mistakes damage engines. Two most common problems – pay attention.

Thread mixing: Toyota uses UNF 3/4-16 inch threads. BYD and others use M20 metric threads. They look similar but NEVER interchange. Wrong fit leaks oil – severe cases cause cylinder scoring.

Hybrid special risk: BYD Song DM-i engine runs intermittently. Oil emulsifies easily. Filter must have good demulsification performance. Ordinary filters fail under this condition.

Our support: Installation instructions with every shipment. After-sales team answers questions online. Helps local repair shops reduce error rates.

Right filter means long engine life. We don’t just sell – we teach you to install correctly.
