Subaru STi Flex Fuel + Fuel Upgrade Package
If you yearn for performance, but also need to use your Subaru STi as a daily driver, you might want to consider flex fuel options. As you may know, E85 is a common fuel used by tuners and gearheads to get more power out of their cars. So a common trend is to install upgrades that allow for the use of E85 fuel types. Ethanol fuels burn cleaner and can typically be cheaper than regular pump gas, but are not always readily available. This can be a major drawback, and more than a few folks have run out of E85 when running an STi that strictly uses E85.
By installing a Subaru STI flex fuel upgrade kit, you are able to use both pump gas and E85. So fill up on Friday on your way to the track, then top it off with Pump gas on Monday morning without having to worry about negative side effects. A STI flex fuel upgrade kit will balance the tune based on the amount of Ethanol detected in the fuel entering the engine. It's as simple as that!
