What It Is Used For
- Replacing a cracked or corroded EGR tube
- Restoring exhaust gas flow between the EGR cooler and EGR valve
- Addressing EGR leak-related drivability concerns
- Correcting emissions system faults tied to tube damage or blockage
- Servicing Subaru EGR cooler-to-valve routing on the listed models
Installation Notes and Tips
Verify the vehicle year, model, and EGR routing before installation. Match the tube length and inner diameter to the original part, and inspect adjoining EGR components for carbon buildup, sealing damage, or corrosion before reassembly. Standard Ignition ETB128 should be installed only on the confirmed Subaru applications listed above.
