Your Subaru's cooling system is only as robust as its weakest link, which is often the aging, OEM coolant hoses that tend to dry-rot. As your Subaru matures, these hoses can deteriorate, leading to cracks that may leave you stranded, be it on the side of the highway or even the racetrack.

Ensuring your vehicle's reliability, whether it's your daily driver or a high-horsepower project, means guaranteeing the integrity of your radiator hoses. They must withstand not just regular conditions but also the heightened temperatures and pressures associated with a high-performance engine. This is where GrimmSpeed makes its mark.

COBB Tuning is a name synonymous with exceptional parts manufacturing and superior quality, known for creating components that can endure the most demanding circumstances. This reputation extends to the brand new COBB Tuning Silicone Radiator Hoses.

These hoses are meticulously crafted using a 5-ply construction method with fiber reinforcement between each layer of silicone, ensuring they maintain their shape and durability throughout the vehicle's life. The COBB Tuning Silicone Radiator Hose Kits were designed through a reverse engineering process, utilizing brand new factory hoses to guarantee a perfect fit, eliminating the need for trimming or kinking during installation. These kits are available in black or red, bearing the distinctive COBB logo embedded into each piece, and are compatible with a range of Subaru applications. Each kit consists of an upper hose, a lower hose, and four high-torque stainless steel clamps from BREEZE.

We take immense pride in our products and the reputation they hold, so, in line with all our manufactured parts, these hoses come with a Lifetime Warranty. They're designed to be the last set of radiator hoses you'll ever need to purchase.
