Subaru owners, this is a genuine OEM oil cooler inlet hose (part number 45520FE070) straight from SUBARU. It's designed to fit certain Impreza models – specifically the 4-door sedan and 5-door wagon from around June 2001 to April 2005. Compatible model codes include GD2, GD3, GD9, GDA, GDB, and a few others. Always double-check your exact vehicle year, grade, and model before ordering, as fit can vary. If your old hose is cracked, leaking, or just worn out, replacing it with this genuine part ensures a perfect fit and reliable performance. Keep your engine's cooling system running smoothly and avoid overheating issues. Genuine parts are built to match the original specs exactly. If you're doing your own maintenance or having a shop replace it, this is the right hose for the job. Keep your Subaru happy!
