    Any recommendations for a good quality Radiator replacement for a 2003 Subaru WRX? I purchased a cheap replacement from O'Reilly's and it lasted less than a year.

    Also, any recommendations regarding hoses?

    Thanks guys!

    Authentic hoses with Koyo OEM, or Koyo Al race, or other Al race style rad. If the Al rad is chosen and your car is automatic you will need a transmission fluid cooler. 5 SPD cars don't. OWM Koyo rads work with either transmission.

    Contact several site vendors and have them make offers vs one another.

    Re: Radiator

    I was luck to find an OE Koyorad on Craigslist for WAY cheap... maybe....

    If it weren't for that I'd had gone with a cheap CX Racing Al radiator(eBay), read good stuff on it. Make sure to replace the hoses and clean the hose mating surfaces while you're at it.
