    OEM fit with no leaks. this combined with my Koyo radiator kept my 04 WRX cool even when pushing it hard in 103 degree heat. Good value

    5out of 5stars

    bought this for my 2004 wrx but thought it wouldn't fit since it's for sti. Customer service went online found some one who had installed one on my same car then emailed and called to let me know where I could find the info as well as offering to send me the wrx pump if I preferred. Installed this with my timing belt and pulleys. Fit perfect and works great. Direct bolt in no modifications. Thanks for all the help.

    • Q: gasket  wtdash4 years ago

      Hi, Is the WP gasket the metal one that Subaru sells? Or paper, etc.? Thanks Wd
    • Q: OEM part numbers?  wtdash4 years ago

      Hi, From '02 WRX - 2015 - EJ205, EJ255 and EJ257 there are 3 different part numbers for the WRX and STi's Water Pumps. This fits ALL ? OEM part #: 21111AA026 - '02-'05 WRX 2.0 / EJ205 21111AA240 - '04-'15 Sti 2.5 / EJ257 and '06-'07 WRX 2.5 / EJ255 21111AA250 - '08-'14 WRX 2.5 EJ255 How is that possible? Thanks

        A:  There are various EJ model engines, but Subaru has created them to still be compatible with this pump. Please enter your vehicle into our excellent filter to determine if this will be a confirmed fitment for your application. Best of luck!

      Will I have trouble with it on my 2009 forester XT(SH9)? Thanks!
      • 1 of 1 people found the following answer helpful

        A:  This is not the correct water pump for a 2009 Forester XT and the correct part number for your car is GAT 42030.

    • Q: Replacement or performance?  Offshore246 years ago

      I see that you have already stated that this pump will perform comparably to the OEM pump. My question is this: was this pump designed and intended to be an OEM replacement (if the OEM pump goes bad) or was this pump designed to replace the OEM pump with added flow rate/cooling performance? Thank you.
      • 4 of 4 people found the following answer helpful

        A:  This is a OEM replacement pump that is made to OEM spec. It is not a performance upgrade and is exactly what Subaru uses. The flow capacity will be the same as stock units
