Smart Roadster Silicone Radiator Induction Hose Set, 3 Pieces

Upgrade your Smart Roadster's cooling system with the Silicone Radiator Induction Hose Kit (3 pieces). This premium kit is designed to directly replace worn OEM hoses, delivering superior heat resistance, reliable sealing, and enhanced performance under demanding driving conditions. Compatible with Smart Roadster 2003–2006, including two-seat and turbo variants, this 3-piece silicone hose set ensures consistent coolant flow and peace of mind during spirited drives.

Crafted from high-quality silicone and built with a robust 3-ply construction, these hoses resist heat, pressure spikes, and aging far better than standard rubber hoses. With a working temperature range of -65°F to 500°F (-54°C to 260°C) and a working pressure of 0.3–0.9 MPa, they keep your engine cool even when boost levels rise. The hoses burst at 245 PSI, providing a generous safety margin for performance upgrades. Each hose is 4.5 mm thick, offering reliable durability in a compact, precise fit.

Originating from Mainland China, this kit is sized to fit the Smart Roadster 2003–2006 two-seat and turbo configurations. The set includes three hoses that align with the original routing, helping you maintain factory-like performance with an aftermarket upgrade.

All electronic and mechanical equipment, devices and machines sold by InterCyprus to EU countries are CE certified and carry a two year warranty.
