What It Helps Address

• Cracked or leaking EGR tube sections
• Restricted exhaust gas recirculation flow
• Emission control fault codes related to EGR routing
• Exhaust leaks at the tube connection points
• Failed inspection due to EGR system issues

Installation Notes and Tips

Confirm the vehicle year, model, and original tube dimensions before installation. For best results, compare the 0.400-inch inner diameter and 9-inch length to the removed part and inspect adjoining EGR components for wear, carbon buildup, or damage. On Subaru WRX, WRX STI, and Impreza applications, proper alignment of the tube is important to maintain a secure seal and correct exhaust gas flow.

Quality Assurance

Standard Ignition supplies ETB123 as a cataloged replacement emission control component for the listed Subaru applications. Verify fitment against the vehicle’s original part number and system configuration before service.
