The Subaru WRX is a beloved vehicle among car enthusiasts, especially those who seek to enhance its performance through modifications. One of the most effective ways to boost the power and reliability of a WRX is by upgrading its turbocharger and intercooler system, particularly when using a flex fuel kit. This article explores the best turbochargers and intercoolers available for the WRX flex fuel kit, ensuring you get the most out of your vehicle.
Understanding Turbochargers
A turbocharger is an essential component that increases an engine’s efficiency and power output by forcing more air into the combustion chamber. This process allows for more fuel to be burned, resulting in increased horsepower and torque. For WRX owners, selecting the right turbocharger is crucial for maximizing performance.
Factors to Consider When Choosing a Turbocharger
- Size and Type: The size of the turbocharger affects boost levels and response time.
- Boost Pressure: Higher boost pressure typically results in more power but may require supporting modifications.
- Durability: Look for turbochargers made from high-quality materials to withstand high temperatures and pressures.
- Compatibility: Ensure the turbocharger is compatible with the WRX flex fuel kit setup.

Understanding Intercoolers
Intercoolers play a vital role in the performance of turbocharged engines. They cool the air compressed by the turbocharger, which increases its density and allows for more oxygen to enter the engine. This results in improved combustion and performance. Selecting the right intercooler is just as important as choosing the right turbocharger.
Key Considerations for Intercoolers
- Core Size: A larger core can provide better cooling, but it may also require modifications for installation.
- Material: Look for intercoolers made from lightweight and durable materials like aluminum.
- End Tank Design: The design affects airflow and efficiency; choose a design that promotes optimal flow.
- Compatibility: Ensure the intercooler fits your WRX model and works well with your turbo setup.
