HPS Performance Silicone Ancillary Hose Kit Black 2005 WRX / 2005 STI | High-Temperature Silicone | Coolant Hose Kit
Overview
The HPS Performance Silicone Ancillary Hose Kit is a direct replacement solution for the ancillary coolant hoses on the 2005 Subaru Impreza WRX 2.0L Turbo and WRX STI 2.5L Turbo models. Designed specifically for these platforms, this kit addresses common issues such as coolant leaks and engine overheating caused by aging or damaged OEM rubber hoses. It is ideal for Subaru enthusiasts looking to maintain or improve the reliability of their cooling system with a durable, high-quality upgrade.
Engineered with precision, the hoses feature the correct bends and curves to ensure a perfect fit without modification. Constructed from reinforced high-temperature silicone, these hoses are built to withstand extreme heat conditions up to 350°F, far exceeding the capabilities of standard rubber hoses. The kit also includes stainless steel embossed hose clamps designed to secure the hoses without damaging them, reflecting HPS Performance’s commitment to quality and longevity.
For Subaru owners, maintaining optimal coolant flow and preventing leaks is critical to preserving engine performance and reliability, especially under demanding driving conditions. This silicone hose kit offers enhanced durability and resistance to heat and pressure, helping to avoid common cooling system failures. While silicone hoses have a higher water permeation rate than rubber, regular coolant level checks ensure consistent engine cooling and peace of mind for daily drivers and track enthusiasts alike.
