This kit is specifically designed to allow your Subaru to run on E85 ethanol fuel or a combination of gasoline and ethanol, providing a more eco-friendly and cost-effective alternative to traditional gasoline.

The heart of this kit is the Cobb Accessport V3 or V3-Pro ECU programmer, which comes pre-loaded with tuning maps optimized for E85 fuel. The Accessport V3 is a handheld, user-friendly device that allows you to adjust various engine parameters on the fly, providing real-time data monitoring and customizable settings.

The kit also includes a high-quality 34mm Bosch fuel pressure regulator, which is designed to maintain consistent fuel pressure for optimal engine performance on E85. The fuel regulator is easy to install, with clear instructions provided, and is constructed from durable materials to ensure long-lasting reliability.

Another essential component of the Nexgen Flex Fuel Kit is the Cobb 60mm Mass Airflow Sensor, which is designed to accurately measure the amount of air entering the engine when running on E85. This sensor is crucial for ensuring proper fuel-air mixture and optimal engine performance. The sensor housing includes a built-in temperature sensor, which helps maintain accurate airflow readings in various operating conditions.

The Nexgen Flex Fuel Kit is compatible with various Subaru WRX and STI models from 2008 to 2021, including those with automatic and manual transmissions. The kit includes all necessary hardware and installation instructions, making it a straightforward and hassle-free upgrade process.

In summary, the Cobb Tuning Nexgen Flex Fuel Kit for Subaru WRX and STI models offers a cost-effective and eco-friendly way to enhance your vehicle's performance. With its easy-to-use Accessport V3 programmer, high-quality fuel pressure regulator, and accurate mass airflow sensor, this kit provides the perfect solution for Subaru enthusiasts looking to explore the world of ethanol fuel.

The Cobb Tuning Nexgen Flex Fuel Kit is a popular aftermarket accessory for Subaru WRX and STI models from 2008 to 2021. This kit allows the vehicle to run on E85 ethanol fuel or gasoline, providing potential performance benefits and reducing reliance on traditional gasoline. Here are some pros and cons of this kit:

1. Fuel Flexibility: The primary advantage of this kit is the ability to run on E85 or gasoline, providing more fuel options and potentially better performance with ethanol.

2. Improved Performance: Ethanol fuel can provide more power and torque than gasoline due to its higher octane rating. Cobb Tuning offers calibrations optimized for E85, which can result in increased horsepower and torque.

3. Reduced Emissions: Ethanol fuel burns cleaner than gasoline, reducing harmful emissions and contributing to a greener driving experience.

4. Reduced Cost: Ethanol fuel can be less expensive than gasoline, especially in areas with a high concentration of ethanol production or availability.

5. Longevity: Ethanol fuel can be gentler on the engine compared to gasoline, potentially extending the life of the engine.

1. Installation Complexity: Installing the Cobb Tuning Nexgen Flex Fuel Kit involves removing the fuel pressure regulator, fuel rail, and other components. This process can be time-consuming and requires a fair amount of mechanical expertise.

2. Fuel Availability: E85 ethanol fuel may not be readily available in all areas, making it a less convenient fuel option for some drivers.

3. Compatibility: Not all Subaru WRX and STI models are compatible with this kit. Check with Cobb Tuning or a professional mechanic to ensure your vehicle is eligible.

4. Cost: The cost of the kit, along with the potential need for additional modifications (such as fuel injectors or a larger fuel pump), can be a significant investment for some.

5. Maintenance: Ethanol fuel may require more frequent maintenance than gasoline due to its higher water content, which can lead to corrosion.

In conclusion, the Cobb Tuning Nexgen Flex Fuel Kit offers several advantages, including improved performance, reduced emissions, and fuel flexibility. However, it also comes with some disadvantages, such as installation complexity, fuel availability, compatibility, cost, and increased maintenance requirements. Ultimately, the decision to purchase this kit depends on the individual's priorities and driving habits. If you frequently have access to E85 fuel and are willing to invest in the installation and potential modifications, this kit could provide significant benefits. However, if the complexities and costs outweigh the benefits for you, it may be best to stick with traditional gasoline.
