HPS Performance Products 57-1660-BLUE High Temp 3-Ply Reinforced Silicone Heater Coolant Hose Kit Blue

The HPS Performance Products 57-1660-BLUE is a high temp, 3-ply reinforced silicone heater coolant hose kit engineered to replace deteriorating OEM rubber heater hoses. Built with premium-grade silicone and a race-proven design, this kit delivers lasting durability and reliability that outlasts stock rubber hoses for both daily drivers and competition vehicles.

Key Features:

• High-Temperature Rated: Withstands extreme under-hood conditions with a maximum temperature rating of 350°F (177°C), engineered for prolonged exposure to both ambient and coolant heat
• 3-Ply Reinforced Silicone Construction: Premium-grade multi-ply silicone reinforced with high-quality polyester braid reduces the risk of failure and maintains integrity under high temperature and high pressure
• Perfect-Fit Design: Molded with the correct bends and curves to match OEM routing exactly — no trimming or modification required, unlike generic universal hoses
• Includes Stainless Steel Hose Clamps: Kit comes with 100% stainless steel industrial-grade non-perforated embossed hose clamps that grip securely without cutting into the silicone hose
• OEM Replacement Quality: Meets or exceeds OE specifications, directly replacing stock rubber heater coolant hoses that can crack, collapse, or weaken over time
• Blue Finish: Vibrant blue color provides a clean, performance look under the hood
• Limited Lifetime Warranty: Backed by HPS Performance Products' limited lifetime warranty when used with included HPS clamps

Important Note: Silicone hose coolant permeation rate is higher than standard EPDM rubber hose. When using silicone coolant hoses, regularly monitoring coolant level is recommended.

Whether you're upgrading a track build or simply replacing aging OEM hoses before they fail, the HPS 57-1660-BLUE silicone heater hose kit is a reliable, long-lasting solution for your vehicle's cooling system.
