Your Subaru’s cooling system is only as good as its weakest link, commonly that’s the old, dry-rotted OEM coolant hoses. As your Subaru ages and the integrity of those hoses degrades, cracks develop and you can suddenly find yourself stranded on the side of the highway or the racetrack.
Part #: 405322
To keep a car reliable, whether it’s a daily driver or a high-horsepower build, it's important to make sure your radiator hoses are up for the job. They need to be able to handle not only everyday conditions, but also the increased temperatures and pressures of a built motor without bulging, leaking, or altogether blowing up. That’s where GrimmSpeed comes in.
GrimmSpeed has always been synonymous with top-notch parts manufacturing and superior quality, developing parts that can handle whatever you throw at them. Things are no different when it comes to the brand new GrimmSpeed Silicone Radiator Hoses.
These hoses are manufactured using a 5-ply construction system with fiber reinforcement between each layer of silicone to ensure that they maintain their shape and durability for the life of the vehicle. GrimmSpeed Silicone Radiator Hose Kits were designed by reverse engineering brand new factory hoses for a perfect fit and effortless installation without having to trim or kink the pieces. The kits are offered in a black or red color with the trademark GrimmSpeed logo embedded into each one and are available for a variety of Subaru applications. Every kit includes an upper hose, a lower hose and four stainless steel high-torque clamps from BREEZE.
We take pride in our products and the name that stands behind them, so as with all of the parts we manufacture, these units come with a Lifetime Warranty and will be the last set of radiator hoses you’ll have to buy.
Quick Specs
Fitment
Looking great! Needs some slight trimming but works amazingly well. Highly recommend. The competition is lesser quality. Look no further
Way thicker than OEM!
Much better quality than oem. Don’t risk blowing a coolant hose and get these nice grimmspeed ones. Also adds a nice little touch to your engine bay
Fit perfect, I have the Killer B water pump housing so I had to do some trimming on the lower hose but it was pretty easy and didn’t take much time. Great addition to the Koyo Rad I bought👌
Picked these up to go with my new CSF radiator on my '13 Forester XT and these worked great and feel like a really good quality.
Great product to replace the stock hoses. Fits perfectly and is high quality. Looks great and a welcomed addition.
Ordered these to go with my new engine rebuild, a lot more substantial than the OEM, and gives the engine a nice sleek look with the shiny finish and the "GS" logo.
