Description
The Mishimoto MMHOSE-TT-99BK is a black silicone radiator hose kit engineered specifically for the Audi TT 1.8T, built with a dual-layer construction of high grade silicone and heat-resistant embedded fibers. This isn’t a generic aftermarket hose stretched to fit — it’s a Mishimoto Cooling component designed to replace the factory hoses with an OEM replacement fit while raising the bar on heat and pressure tolerance.
Where factory rubber hoses degrade over time from constant heat cycling, this Mishimoto radiator hose kit uses reinforced silicone construction rated to a maximum temperature of 330°F to efficiently reduce heat and increase pressure tolerance in the cooling system. As a Performance grade, vehicle-specific silicone hose, it’s built to handle the demands of daily driving or spirited use without sacrificing the factory fit and finish, and it’s also available in blue or red for owners who want to match their engine bay color scheme. Backed by the Mishimoto Lifetime Warranty, this hose kit is a straightforward upgrade for anyone looking to refresh a tired or cracked cooling system with a durable, OEM-fit silicone solution.
Vehicle Applications
This Mishimoto radiator hose kit is a direct, vehicle-specific fit for the Audi TT lineup. It covers the Audi TT Base and Audi TT Quattro Base from 2000 through 2006, along with the Audi TT Quattro ALMS Edition for the 2002 model year and the Audi TT Quattro Special Edition for 2006. Because this is a specific-fit hose kit rather than a universal design, it’s engineered to match the factory routing and connection points on these Audi TT applications.
