Construction & Design:
The hoses are manufactured using premium-grade silicone reinforced with three layers for enhanced durability and heat resistance. This construction ensures the hoses maintain their shape and integrity under extreme thermal stress and pressure. The kit’s hoses are precision-engineered with factory-correct bends and curves, eliminating the need for any cutting or modifications during installation.
The included stainless steel clamps are embossed and non-perforated, which prevents them from cutting into the silicone material, ensuring a secure and leak-free seal over time. This combination of materials and design choices results in a reliable, long-lasting cooling system upgrade that performs well under demanding conditions.
