Radiator Hose Kit Silicone For Mazda MX-5 NB 1.8L Engine Cooling, High-Heat Resistant 1998-2004
Upgrade your Mazda MX-5 NB 1.8L cooling system with a Silicone Radiator Hose Kit crafted for the 1998–2004 NB models. These premium silicone hoses replace the OEM rubber hoses, delivering superior heat resistance, reduced risk of swelling, and enhanced durability under everyday driving or spirited driving sessions. The kit’s three-ply construction and 4.5 mm wall thickness keep coolant flowing smoothly, even when the engine runs hotter than stock.
Engineered for reliability, the hoses operate across a broad temperature range from -65°F to 500°F (-54°C to 260°C) and handle a working pressure of 0.3–0.9 MPa, with a bursting pressure of 245 psi. This performance margin helps protect your cooling system from leaks and failures during high-load conditions, making it a smart upgrade for boosted builds or vehicles exposed to demanding driving environments.
This kit is a direct replacement designed to fit Mazda MX-5 NB 1800cc engines (1998–2004), aligning with OEM hose paths and clamps for an easy, drop-in installation. Made in Mainland China, each hose is manufactured to tight tolerances (±0.5 mm) to ensure a precise fit and dependable seal. By choosing silicone, you gain improved resistance to heat, oil, and coolant chemicals, plus longer service life compared with traditional rubber hoses.
