    Has the annoying drain plug baffle 7 years ago
    3out of 5stars

    Ok so I bought this pan just to put a nice new clean pan on my STI when i had the motor out anyway for a full rebuild. There is nothing wrong with the pan as far as product quality ect goes, it is just a normal oil pan and it fits my killer b oil pickup as expected, and in those regards I am happy. BUT it was the pan from that year or 2 that has the baffle over the oil drain plug we nicknamed the shower pan because it makes a mess when you drain the oil. I wish it was just a normal 2.5 turbo pan, i thought this pan only came on the legacy but I could be wrong. I probably would not have put the pan on but i didn't even notice the baffle until I put the motor back in the car and did the first oil change after startup lol.

        A:  We recommend using MOR 24965 as a pickup tube when using the OEM STi pan as well as sourcing an STi dipstick.

    • Q: Oil pan  Fozzy_Chris4 years ago

      I need a 2.5 oil pan for my 2004 forester because the stock one doesn't clear the header, will this pan work?

        A:  This should bolt up just fine. Subaru does not confirm fitment on your vehicle though.

    • Q: 2005 WRX  stopher55 years ago

      What pickup is required for an EJ20? In addition to the STi dipstick, is there anything else needed for this swap?

        A:  You will need the Subaru OEM Oil Pickup Tube For STI Pan Subaru WRX / STI 2002-2007. You will also need a tube of Subabond to seal the new pan.

    • Q: Killer b fitment  darthanis5 years ago

      Will this work with the 070-110 killer B pickup? From what I'm reading the answer seems to be yes but I would like to verify.
