Restore Damaged Sensor Ports on Your DPF

-
Pressure-tested for accuracy
-
Compatible with most filter types
Replace the Filter Core—Not the Housing
Recore
When your filter’s ceramic core is damaged beyond cleaning, we recore it—swapping in a new substrate and sealing it inside your existing shell. It's the cost-effective way to start fresh.

Perfect for melted or damaged cores
