Product Description

When it’s time to replace the factory radiator hoses on your 2002-2007 Subaru WRX or 2004-2007 STI, the IAG Silicone Upper & Lower Radiator Hose Kit provides a dependable, long-lasting upgrade over OEM rubber hoses. As rubber hoses age, they can deteriorate—leading to cracks, bulges, and potential leaks that compromise your cooling system. Built with premium materials and precision-engineered design, the IAG hose kit withstands extreme temperatures and wear, offering durability your factory components just can’t match.

Constructed from 4-ply reinforced silicone and measuring 5mm thick, the IAG Silicone Upper & Lower Radiator Hose Kit is built to handle extreme heat, resist chemical breakdown, and outlast standard rubber hoses. Available in black, red, or blue, each hose features a pre-formed shape for a perfect fit that won’t pinch or collapse under pressure. Tough enough for competition use, these hoses provide reliable cooling performance on the street or at the track—even in the most demanding conditions.

The IAG Silicone Upper & Lower Radiator Hose Kit is a direct replacement for the upper and lower OEM radiator hoses on the 2002-2007 Subaru WRX or 2004-2007 STI (GD chassis), with pre-formed bends that fit just like factory. Designed for a precise fit at the radiator inlet, outlet, and engine ports, these hoses install easily with no modifications required. The kit also comes with stainless steel clamps for a strong, reliable seal.
