Let’s talk about keeping your Subaru running smoothly, especially when it comes to something as crucial as the cooling system. You know how it goes—those OEM coolant hoses can get old and brittle over time. One minute you’re cruising down the highway, and the next, you’re stuck on the side of the road because a hose decided it was time to give up. Not ideal, right?
If you want your ride to stay reliable, whether you're using it for daily commutes or pushing the limits on the track, you’ve got to make sure those radiator hoses are up to the task. They need to handle the heat and pressure that come with a tuned engine without bursting or leaking. That’s where GrimmSpeed steps in.
GrimmSpeed has built a solid reputation for crafting high-quality parts that can take a beating, and their new Silicone Radiator Hoses are no exception. These bad boys are made with a robust 5-ply construction, featuring fiber reinforcement between each layer of silicone. This means they won’t lose their shape or durability, no matter how hard you push your Subaru.
The cool part? These hoses are designed with precision in mind. GrimmSpeed reverse-engineered the factory hoses to ensure a perfect fit, so you won’t be wrestling with trimming or kinking when you install them. Plus, you can choose between a sleek black or a bold red, both sporting the iconic GrimmSpeed logo. Each kit comes with an upper and lower hose, along with four stainless steel high-torque clamps from BREEZE to keep everything secure.
Features:So, if you’ve got a 2014-2017 Forester XT or a 2015-2017 WRX, the GrimmSpeed Black Radiator Hose Kit (part number 405324) is just what you need to keep your cooling system in check. Don’t let old hoses leave you stranded—upgrade to GrimmSpeed and ride with confidence!
