    QUESTIONS & ANSWERS

    • Q: Fuel Rail Compatibility   Reid Longo9 months ago

      Are these fuel rails for top feed or side feed TGV’s?
    • Q: Fitment   07STIlimited1 year ago

      will this product fit 07 sti?
      • 0 of 0 people found the following answer helpful

        A:  It will not fit. The Flex Fuel/Pressure sensors for your 07 are kit number: COBSUBFFGD002, the injectors are COB312150, and the fuel pump is AEI50-1220. As for the lines, rails, and regulator, Cobb unfortunately does not make them for your vehicle, but there are brands that make line/rail/regulator setups that work with Cobb's Flex Fuel setup. Feel free to contact our customer service team for guidance on your setup.

    • Q: Flex Fuel  Synapse3 years ago

      Rumor has it that since this is a "Flex Fuel" package, you will be able to run on E85 as well as regular 93 octane pump gas. Obviously a protune is required with this kit, but apart from that, would it be necessary to switch maps/make adjustments if you switch from ethanol to pump gas? Or would the tuner "build in" the necessary adjustments into the tune, based on what the ethanol sensor is reading?
      • 2 of 2 people found the following answer helpful

        A:  The Cobb Flex Fuel Kit will be able to measure the Ethonal/Gasoline mixture and make adjustments accordingly. The Protuner will be able to configure this using the Cobb AcessPort.

        A:  there are some vids on yt showing the AP shifting ethanol % as he fills up from 93 to e85 and its pretty cool. the ap knows what you give it and changes the mapping accordingly, pretty siiiick
