AEM High Flow Fuel Pump: It's tested at 340lph @ 40psi, compact in size, and compatible with ethanol fuels up to E100, methanol fuels up to M100, and all types of gasoline.
Using the COBB NexGen Stage 2 Flex Fuel Power Package is a great way to enhance your Subaru STI's performance. First, when installing, follow the installation guides that come with each component carefully. The Accessport V3 can be easily mounted in your vehicle using the provided in - vehicle mount and on/off switch. It's user - friendly, so you can quickly customize the multi - gauge display according to your preferences. The Redline Carbon Fiber Intake is a bit special. It looks great with its carbon fiber weave and gloss finish, but remember it doesn't fit with the COBB Radiator Shroud. And you'll need to do some tuning after installation. For the fuel - related components like the fuel injectors, fuel rails, and fuel pump, make sure to connect them correctly as they are crucial for the proper fuel delivery of your car. The turbo inlet and throttle body coupler can improve your car's power and response, but tuning is also required for them. When it comes to maintenance, regularly check the fuel pressure sensors and spark plugs. Replace the spark plugs as recommended by the manufacturer, usually when they show signs of wear. Also, keep an eye on the silicone parts like the turbo inlet and throttle body coupler for any signs of damage or aging. If you're using ethanol - based fuels, make sure all the components are well - maintained as ethanol can be a bit more corrosive than regular gasoline. Overall, with proper use and maintenance, this power package will keep your Subaru STI running at its best.
