The Subaru WRX is known for its performance and tuning potential, especially when it comes to E85 conversion. One of the most effective ways to enhance performance is through intercooler and intake upgrades. These modifications not only support higher boost levels but also improve overall engine efficiency. In this article, we will explore the best intercooler and intake upgrades for WRX E85 conversion.
Understanding E85 and Its Benefits
E85 is a fuel blend that contains 85% ethanol and 15% gasoline. It offers several advantages for performance enthusiasts:
- Higher Octane Rating: E85 has a higher octane rating than regular gasoline, allowing for more aggressive tuning and higher boost levels.
- Cooling Properties: Ethanol has a higher latent heat of vaporization, which helps cool the intake charge and reduces the chances of knock.
- Cleaner Combustion: E85 burns cleaner than gasoline, resulting in fewer emissions and potentially longer engine life.
Importance of Intercoolers
The intercooler plays a crucial role in any turbocharged engine setup, especially when running higher boost levels. Here’s why upgrading the intercooler is essential for E85 conversions:
- Temperature Reduction: An upgraded intercooler provides better heat dissipation, lowering the intake air temperature and improving performance.
- Increased Airflow: A larger intercooler allows for more airflow, which is critical for maximizing the benefits of E85 fuel.
- Enhanced Reliability: With lower temperatures, the engine components experience less stress, leading to improved reliability under high-performance conditions.

Understanding Intake Upgrades
The intake system is another critical component that can significantly impact the performance of a WRX, especially when converting to E85. Upgrading the intake allows for better airflow and improved throttle response.
- Improved Airflow: A performance intake system can increase the volume of air entering the engine, which is essential for maximizing E85’s potential.
- Better Throttle Response: Upgraded intakes can enhance the engine’s responsiveness, providing a more engaging driving experience.
- Sound Enhancement: Many performance intakes also provide a more aggressive sound, adding to the overall driving experience.
