Radiator Outlet Hose (Lower) – Genuine Subaru 45161AE020

Keep your EJ cool under pressure with the genuine Subaru lower radiator hose.
This hose carries coolant from the radiator back into the engine — a critical line that takes the heat of every drive.

Old hoses get brittle, bulge, or crack near the clamps. When they go, you’re stuck. Replace it with the real deal and restore your cooling system to factory reliability.

Fits:

• Impreza WRX / STI (2001–2007)
  Compatible with: EJ201, EJ204, EJ205, EJ207, EJ251, EJ255, EJ257 engines.

OEM Part Number: 45161AE020

Why Genuine Subaru:

• Factory-grade rubber for high heat and pressure resistance

• Direct OEM fit — no trimming or guesswork

• Maintains steady coolant return flow for consistent temps

• Trusted Subaru quality for daily driving and performance builds

Roo Racing Tip:
Always replace upper and lower hoses together. A cooling system is only as strong as its weakest link — and this small part keeps your big investment safe.
