Product Description
The HPS Performance Silicone Ancillary Coolant Hose Kit (part number 57-2303) is designed to replace your 2004 Subaru Impreza WRX STI 2.5L Turbo old or damaged ancillary coolant hoses. It features premium high-heat resistant material that meets or exceeds OE specifications, with a maximum temperature rating of 350F. Unlike universal hoses from local parts stores, HPS silicone hose kits are engineered with precise bends and curves for a perfect fit. For easy installation, this kit includes 100% stainless steel, non-perforated embossed hose clamps that will not cut through the silicone hoses.
HPS silicone hoses can fix and prevent coolant leaks and engine overheating problems often caused by cracked, damaged, or collapsed OEM rubber coolant hoses. Excellent for extreme ambient and radiant temperature conditions, these silicone hoses withstand the harsh high temperatures and high-pressure operating conditions of the engine. This ensures your engine maintains peak efficiency during daily driving or racing competition.
While HPS high temperature 3-ply reinforced silicone radiator, heater and ancillary hose kit (part number 57-2304) replaces 2004 Subaru Impreza WRX STi 2.5L Turbo stock OEM rubber lower and upper radiator hoses, heater hoses and ancillary coolant hoses with high-heat resistance material which meets or exceeds OE specifications (Maximum temperature rating: 350F).
