This is the GrimmSpeed Radiator Hose Kit. These radiator hoses feature multi-layer silicone construction that is built to last while improving the overall cooling efficiency of your vehicle. Your factory radiator hoses over time and mileage endure multiple heat cycles and what happens is that the fibers will break apart causing the hoses to expand which can cause a leak. The GrimmSpeed units are super durable with heat-resistant properties with fiber-reinforced construction to provide you with a quality and reliable product that is built to last.
