Many customers have praised the GrimmSpeed Silicone Radiator Hose Kit for its reliability and ease of installation. One user noted, "I installed these hoses on my WRX, and the fit was spot on. No trimming needed, and they look great too!" Another customer shared, "I feel much more confident in my cooling system after swapping out the old hoses for these. They handle the heat like a champ!"
The kit includes an upper and lower hose, along with four stainless steel clamps. This ensures that you have everything you need for a complete installation right out of the box.
