Construction & Design:

The Mishimoto radiator hoses are crafted from premium 4-ply silicone reinforced with heat-resistant fibers, ensuring superior strength and flexibility. This construction allows the hoses to endure extreme under-hood temperatures and high coolant system pressures without cracking, swelling, or collapsing. The internal spring in the lower hose mimics the factory design to prevent hose collapse during high vacuum conditions, a critical feature for maintaining consistent coolant flow and engine temperature regulation.

The one-piece design of the secondary hoses replaces the factory Y-connector, a common failure point, providing a more robust and reliable solution. The black silicone finish not only offers a clean, professional look but also resists fading and discoloration over time.
