Product Description

The Skunk2 Silicone Radiator Hose Kit (629-05-0009) is a direct OEM-fit replacement for the factory rubber cooling hoses on the 2002-2005 Honda Civic Si (EP3). Each hose is handmade from multi-layer, fiber-reinforced automotive-grade silicone that resists the heat, pressure, and chemical exposure that cause OEM rubber hoses to crack and deteriorate over time. With a gloss black exterior, red interior, and embossed Skunk2 logo, the kit delivers a clean, finished engine bay aesthetic alongside a genuine performance and reliability upgrade.

Skunk2 individually test-fits each application to ensure precise alignment with the EP3's OEM water neck, thermostat housing, radiator, and factory hose clamps - making installation straightforward with no cutting or modification required. For enthusiasts looking to maximize cooling efficiency, Skunk2 recommends pairing this hose kit with a Skunk2 Radiator Cap, which raises internal system pressure for a higher coolant boiling point and more effective heat dissipation.
