The Subaru WRX is a beloved car among enthusiasts, known for its performance and tuning potential. When upgrading to a Stage 2 setup, one of the most critical components to consider is the intercooler. A high-quality intercooler can significantly enhance performance by improving air intake temperatures and increasing power output. In this article, we will compare three popular front mount intercoolers (FMICs) for the Stage 2 WRX: TurboXS, GrimmSpeed, and APS.
Understanding Front Mount Intercoolers
Before diving into the comparisons, it’s essential to understand what a front mount intercooler does. An intercooler cools the air coming from the turbocharger before it enters the engine. Cooler air is denser, allowing for better combustion and increased horsepower. FMICs are typically larger and more efficient than stock intercoolers, making them a popular choice for modified vehicles.
TurboXS Front Mount Intercooler
The TurboXS FMIC is designed for high performance and durability. It features a large core that significantly improves cooling efficiency. Here are some key features:
- Core Size: 3” thick core for maximum cooling.
- Construction: Made from high-quality aluminum for lightweight durability.
- Installation: Direct bolt-on design for easy installation.
The TurboXS intercooler is known for its ability to maintain lower intake temperatures even during aggressive driving. This feature can help prevent heat soak, which is critical for maintaining performance during long sessions on the track.
Performance and Results
In testing, the TurboXS FMIC has shown impressive results, often yielding a noticeable increase in horsepower and torque. Users have reported gains of up to 25 horsepower with proper tuning. Additionally, the intercooler’s design allows for minimal pressure drop, ensuring that the turbocharger can deliver maximum boost efficiently.
GrimmSpeed Front Mount Intercooler
The GrimmSpeed FMIC is another excellent option for Stage 2 WRX owners. It is designed with performance in mind and offers several unique features:
- Core Size: 3.5” thick core for superior cooling.
- Construction: High-grade aluminum with a powder-coated finish for added protection.
- Installation: Includes all necessary hardware for a straightforward installation.
One of the standout features of the GrimmSpeed intercooler is its ability to reduce intake temperatures significantly, even under high-load conditions. This improvement can lead to better throttle response and overall engine performance.
Performance and Results
Users of the GrimmSpeed FMIC have reported impressive performance gains as well, with some experiencing increases of around 30 horsepower. The intercooler’s efficiency at cooling has been praised, especially during extended driving sessions, making it a solid choice for track enthusiasts.
APS Front Mount Intercooler
The APS FMIC is a premium option that offers a blend of performance and aesthetics. It is designed to provide excellent cooling while maintaining a sleek look. Here are some of its key features:
- Core Size: 3” thick core optimized for airflow.
- Construction: Lightweight aluminum with a polished finish.
- Installation: Designed for a direct fit with minimal modifications.
The APS intercooler is particularly noted for its stylish design, which can enhance the overall appearance of your WRX while delivering performance benefits. It features a unique end tank design that improves airflow efficiency.
Performance and Results
Performance-wise, the APS FMIC also delivers solid gains, with reports of up to 25 horsepower increase. Its efficient cooling capabilities make it suitable for both daily driving and track use, providing a reliable performance boost without sacrificing reliability.
Comparative Analysis
When comparing the TurboXS, GrimmSpeed, and APS FMICs, several factors come into play:
- Cooling Efficiency: All three intercoolers offer excellent cooling, but GrimmSpeed tends to edge out slightly with its larger core size.
- Installation: TurboXS and APS are noted for their straightforward installation processes, while GrimmSpeed includes all necessary hardware.
- Performance Gains: All three options provide substantial performance increases, with GrimmSpeed often reported to deliver the highest gains.
Ultimately, the best choice will depend on your specific needs and preferences. If you prioritize aesthetics along with performance, the APS might be the right fit. For maximum cooling efficiency, consider the GrimmSpeed, while TurboXS offers a solid balance between performance and ease of installation.
Conclusion
Choosing the right intercooler for your Stage 2 WRX is crucial for optimizing performance and ensuring reliability. The TurboXS, GrimmSpeed, and APS FMICs all provide excellent options, each with unique features and benefits. Consider your driving style, installation preferences, and aesthetic desires when making your decision. With the right intercooler, you can unlock the full potential of your WRX and enjoy an exhilarating driving experience.
