Silicone Top & Bottom Radiator Hoses WRX & STI 01-07

This Fuji Racing silicone radiator hose kit replaces your aging factory rubber with high-performance, heat-resistant silicone that won’t split, sag, or slowly bleed coolant under load. Built for the EJ crowd that actually drives their cars, this kit delivers long-term reliability and clean, track-inspired looks in one upgrade.

Each hose is handmade using custom jigs to ensure consistent fitment across every kit. Lined for OAT coolant compatibility and rated from -150°C to +230°C, these hoses hold up to the worst heat cycles you can throw at them—on or off boost.

🔧 Direct fit for WRX & STI 01–07 – No cutting or trimming required
🔥 OAT coolant ready – Safe for all modern Subaru fluids
🧵 Hand-finished and pressure tested – No shortcuts, no fails
