Detailed Review
The RATCHROLL Upper Radiator Inlet Hose serves as a direct replacement component for worn or failing factory cooling lines. Designed specifically for targeted Subaru models, this component routes coolant into the radiator to maintain standard engine cooling operations.
Made of black rubber, this inlet hose matches original equipment specifications and corresponds to OE number 45161AG000. It covers a specific span of vehicles, including the 2008 to 2011 Subaru Impreza 2.5L, the 2008 to 2010 Subaru Forester 2.5L, the 2008 to 2014 Subaru WRX, and the 2008 to 2021 Subaru WRX STI.
Installation is straightforward, requiring you to remove the existing hose and put the new unit in its place. Note that the package includes only the single rubber hose, so any hose clamps or additional hardware from the original setup must be reused or sourced separately.
Verdict: The RATCHROLL Radiator Inlet Hose is a practical replacement for owners needing to replace OE part 45161AG000 on compatible Subaru Impreza, Forester, WRX, or WRX STI vehicles.
