OBX 100% Silicone Radiator Hose Kit | 00-05 Mitsubishi Eclipse V6 | 2-Pc Kit
This OBX RH08R 2-piece silicone radiator hose kit is designed for 2000-2005 Mitsubishi Eclipse and Eclipse Spyder models equipped with the 3.0L V6 6G72 engine. The kit includes the upper and lower radiator hoses and follows the factory-style cooling-system routing for the application described below.
Each hose is manufactured from 100% pure silicone with multi-layer nylon reinforcement and a glossy red finish. This reinforced molded construction provides a durable performance replacement for aging factory rubber coolant hoses while giving the engine bay a clean, upgraded appearance.
Confirmed Vehicle Compatibility
2000-2005 Mitsubishi Eclipse / Eclipse Spyder 3.0L V6 6G72
Fits applicable GT, GTS, Spyder GT, and Spyder GTS applications only. Not for 2.4L GS, RS, or Spyder GS models.
See the complete Vehicle Compatibility section below and confirm that the vehicle, engine, hose shapes, and routing match before ordering.
100% Pure Silicone
Molded from 100% pure silicone with a smooth interior and glossy red finish for automotive engine-coolant service.
Multi-Layer Reinforced
Multi-layer nylon reinforcement supports hose strength and dimensional stability. The stated operating range is -165°F to 350°F, with a maximum temperature rating of 350°F.
Install & Clamp Correctly
Install over clean fittings, fully seat each hose, and position a properly sized OEM-style constant-tension or silicone-safe clamp behind the retaining bead. Tighten securely without crushing the silicone, then recheck after the first complete heating and cooling cycles.
Measured & Inspected In House
Kuku Performance photographs the actual kit and verifies its SKU, color, piece count, hose functions, and available connection measurements before shipment.

Hose measurements are approximate and were taken directly from the photographed sample. A molded hose may use different diameters at different ends, and results can vary slightly with caliper placement. Approximate wall thickness is calculated as (outside diameter - inside diameter) ÷ 2 because the hose wall is present on both sides of the opening. Compare the labeled photographs, hose shapes, connection points, and routing with the original hoses before ordering.
