What It Helps Address

• Airflow disruption from a cracked or corroded intercooler assembly
• Replacement needs after impact damage to the front-mounted cooler

Installation Notes and Tips

Verify the vehicle’s front charge air cooler layout before ordering. Compare the hose connector and port locations to the original unit, and transfer any required vehicle-specific components from the existing setup if applicable. Because mounting hardware is not included, reuse or source the correct hardware separately as needed. Confirm fitment against the original part number before installation.

Quality Assurance

Standard Ignition supplies OE-style replacement components for service applications, and CAC28 is specified as an O.E Exact intercooler for the listed Subaru fitments. Confirm the application against the vehicle’s original charge air cooler configuration before installation.
