Description
The Mishimoto MMHOSE-GTO-04BK is a direct-fit silicone radiator hose kit engineered specifically for the 2004 Pontiac GTO. Finished in black and built from a dual-layer construction of high-grade silicone reinforced with heat-resistant embedded fibers, this kit is designed as an OEM replacement for the factory rubber hoses in your GTO’s cooling system.
Cooling system reliability starts with hoses that can handle heat without breaking down over time, and this Mishimoto silicone hose kit is built to do exactly that. The dual-layer silicone and embedded fiber construction is rated to a maximum temperature of 330°F, helping the hoses efficiently manage heat under the strain of daily driving or spirited performance use. As a performance-grade, vehicle-specific part, it’s made to bolt in as a direct OEM replacement, giving GTO owners a straightforward upgrade path for a cooling system component that’s easy to overlook until it fails.
