So, you've got a 2004 Subaru Impreza WRX and you're tired of dealing with those stock rubber heater hoses that seem to crack and leak at the worst possible moments. Let me tell you, I’ve been there. That’s where the HPS high temperature 3-ply reinforced silicone heater hose kit (part number 57-1803-BLK) comes in. This isn’t just any replacement; it’s a serious upgrade.
First off, these hoses are made from a premium-grade silicone that can handle some serious heat—up to 350°F, to be exact. That’s right, you won’t have to worry about these babies failing when things get hot under the hood. The design is spot-on too, with all the right bends and curves to ensure they fit perfectly without any hassle. No more wrestling with hoses that just don’t want to fit where they’re supposed to.
Installation is a breeze thanks to the included 100% stainless steel non-perforated embossed hose clamps. These clamps are designed not to cut into the silicone, which means you can tighten them down without worrying about damaging the hose. Trust me, that’s a game changer when you’re under the hood trying to get everything just right.
One of the biggest headaches with OEM hoses is the coolant leaks and overheating issues that come from cracked or collapsed rubber. With this silicone kit, you can kiss those problems goodbye. It’s built for durability and can handle prolonged exposure to the heat that comes with daily driving or even a bit of spirited driving on the weekends.
Now, here’s the nitty-gritty: this kit is compatible with OEM part numbers 72421SA033 and 72411FE001, so you know it’s the right fit for your WRX. Plus, it comes with a solid 2-year warranty, which gives you peace of mind that you’re investing in quality.
Just a heads-up though—silicone hoses have a higher water permeation rate than standard EPDM rubber hoses, about 10 to 15 times more. So, if you’re using these in a daily driver, make it a habit to check your coolant levels regularly. It’s a small price to pay for the performance boost you’ll get.
In short, if you want to upgrade your WRX and say goodbye to those unreliable OEM hoses, the HPS silicone heater hose kit is where it’s at. It’s tough, it’s reliable, and it’s designed for folks who know what they want from their ride.
