Is the air conditioning in your classic Subaru WRX or STi not working because of a leaking hose? This is the exact Genuine Subaru OEM replacement high-pressure discharge hose you need (part number 73421FE001). Using the real factory part guarantees a perfect fit and connection to your AC compressor and condenser, with the correct fittings and hose routing. It's designed specifically for the 2002-2007 Subaru Impreza, including the WRX and STi models from those years. Aftermarket AC hoses can sometimes use different seals or have slight fitment issues, so for a critical system like AC where leaks are a headache, going OEM is often the best bet. The part comes sealed in its original Subaru packaging. Just make sure your vehicle matches the fitment list (2002-2007 Impreza/WRX/STi) before ordering. Replacing AC hoses usually requires evacuating and recharging the refrigerant, so this is a job best left to a professional mechanic or auto AC specialist.
