Upper & Lower Radiator Coolant Hose Kit Compatible with 2008-2014 Subaru Impreza (including WRX & STI), 2015-2021 WRX STI, 2009 2010 Forester Replaces 45161AG000 45161AG010

Is your Subaru pushing past 100,000 miles on the original coolant hoses? Factory rubber breaks down from the inside out — daily heat cycling from your 2.5L Boxer engine, coolant chemistry, and pressure spikes slowly weaken the material until a soft spot or full blowout leaves you on the shoulder with steam pouring from under the hood.This Saysalus upper and lower radiator coolant hose kit replaces both critical cooling lines in one purchase. Built from OE-grade EPDM rubber with multi-layer fiber reinforcement, each hose matches factory specifications for precise fitment, flow capacity, and thermal resistance. Pre-molded bends and accurate port sizing mean a direct drop-in installation with no trimming needed.Complete Vehicle Compatibility:Fit For 2009-2010 Subaru Forester 2.5L H4 SOHCFit For 2008-2011 Subaru Impreza 2.5L H4 / 2.5L H4 TurboFit For 2008-2014 Subaru Impreza STI 2.5L H4 / 2.5L H4 TurboFit For 2008-2014 Subaru Impreza WRX 2.5L H4 / 2.5L H4 TurboFit For 2015-2020 Subaru WRX 2.5L H4 TurboFit For 2015-2020 Subaru WRX STI 2.5L H4 TurboFits models equipped with 2.5L H4 Gas Engines (Turbo and Non-Turbo)Replaces OE Part Numbers:Upper Outlet Hose: 45161AG000Lower Inlet Hose: 45161AG010Package Includes:1x Upper Radiator Coolant Hose1x Lower Radiator Coolant Hose

• DIRECT FIT FOR 2.5L SUBARU MODELS: Engineered as a precise OE replacement for 2008-2014 Subaru Impreza (including WRX & STI), 2015-2021 Subaru WRX STI, and 2008-2013 Subaru Forester. Replaces OE part numbers 45161AG000 (upper) and 45161AG010 (lower) with zero modifications required.
• EPDM RUBBER ENGINEERED FOR BOXER ENGINE HEAT: Constructed from OE-grade EPDM rubber with multi-layer fiber reinforcement. These hoses are built to handle the intense thermal demands and pressure spikes of Subaru's 2.5L flat-four engines, resisting the swelling, softening, and internal delamination that cause aging factory hoses to fail.
• PRE-MOLDED FOR A 30-MINUTE GARAGE INSTALL: Precision-molded to replicate the exact routing, bends, and port diameters of the original Subaru parts. No cutting, trimming, or adapter fittings required—simply line up the hose, secure your clamps, refill your cooling system, and get back on the road safely.
• REPLACE BOTH HOSES IN ONE ORDER: When one coolant line ages out, the other is not far behind. This complete kit allows you to refresh your entire radiator-to-engine loop simultaneously, eliminating the risk of a second breakdown weeks later.
• BACKED BY 12-MONTH REPLACEMENT WARRANTY: Every hose set is individually inspected for dimensional accuracy and structural integrity before packaging. If any fitment issue arises or a defect appears under normal driving conditions within the warranty period, we will ship a replacement at no cost.
