HPS silicone hoses can prevent and fix the coolant leaking and engine over heating problem caused by cracked, damaged or collapsed OEM rubber coolant hoses. Excellent for extreme ambient and radiant temperature conditions, HPS silicone hoses can withstand the harsh high temperature and high pressure operating conditions of the engine yet still maintaining peak efficiency during daily driving or racing competition. HPS silicone hose kit is backed by HPS Performance Products limited lifetime warranty.
