Key Features

Engineered for durability and perfect fitment, this hose kit includes:

• Premium grade, 3-ply reinforced silicone construction for superior heat resistance and flexibility
• Precisely molded bends and curves to match OEM hose routing and ensure hassle-free installation
• 100% stainless steel, non-perforated embossed hose clamps that securely fasten without damaging the silicone
• Race-proven design built to withstand prolonged exposure to high under-hood temperatures and coolant heat
• Maximum operating temperature rating of 350°F (177°C) for reliable performance in demanding conditions
• Prevents common issues such as cracking, collapsing, and coolant leaks associated with aging OEM hoses
• Significantly lower permeability to water vapor compared to standard EPDM rubber hoses, requiring regular coolant level checks

Construction & Design

The hoses in this kit are crafted from high-quality silicone reinforced with three layers of fabric to provide exceptional strength and durability. This multi-ply design allows the hoses to maintain shape and resist deformation under pressure and heat, unlike conventional rubber hoses that can become brittle and crack over time. The silicone material also offers excellent resistance to oil, chemicals, and ozone, extending the service life of the cooling system components.

Each hose is engineered with precise bends and contours to replicate the original factory hoses, ensuring a seamless fitment without the need for modifications. The included stainless steel clamps are embossed and non-perforated, which prevents cutting or damaging the silicone surface during installation or maintenance.
