IAG Silicone Radiator Hose Kit Blue 2015-2021 WRX

Over time, factory rubber hoses can harden, crack, or leak—putting your cooling system at risk. The IAG Silicone Upper & Lower Radiator Hose Kit is engineered to withstand the heat and pressure of high-performance driving while offering a clean, long-lasting upgrade over OEM hoses.

Each hose is made from 4-ply reinforced silicone with a 5mm wall thickness for exceptional durability and resistance to heat, pressure, and chemical breakdown. Pre-formed bends ensure a perfect, factory-style fit that won’t kink or collapse under load. These hoses deliver both reliability and a refined engine bay appearance.

Designed as a direct replacement for the upper and lower radiator hoses on the 2015–2021 Subaru WRX, the kit includes stainless steel clamps for a secure, leak-free installation—no cutting or modification required. Built for longevity and performance, it’s equally at home on the street or the track.
