  • Q: 2003 WRX running Cobb Stage 2+  ManCave4 months ago

    Is the correct version for 2003 WRX running Cobb Stage 2+? I am currently running Walbro. Does it require any additional parts or is it a plug and play? Thanks!
    • 0 of 0 people found the following answer helpful

      A:  So I did some digging and it seems that there is not need for fuel system upgrades when you are at a stage 2+ with your WRX. If you were going to get a protune this would be a good option for you.

  • Q: Aem 340lph  Austin 7 months ago

    What kind of power will this pump be capable of?
    • 0 of 0 people found the following answer helpful

      A:  There's several factors that go into it such as fuel type, base fuel pressure, injector size, etc. As a general rule, this will do high 300's to low 400's on ethanol, and roughly mid 400's on pump or race gas.

  • Q: Will I need the plastic hooks?  RogueMTB1 year ago

    For my 2014 WRX, will this pump work or do I need the kit that has the plastic hooks?
  • Q: Will this work in 2007 STi?  HawkeyeSTi072 years ago

    Also how do you wire it? Cut other ones, crimp them to this harness and plug in?
    • 0 of 0 people found the following answer helpful

      A:  Due to this fuel pump being a universal product, we cannot confirm the fitment to any specific application. However, this fuel pump will work with most applications with little or no modification to the fuel pump housing.
