The performance of a Subaru WRX can be significantly influenced by the intercooler system. Two popular options among enthusiasts are the APEXi and Grimmspeed intercoolers. This article will delve into the features, benefits, and performance comparisons of both intercoolers to determine which one offers the best cooling and power for your WRX.
Understanding Intercoolers
Intercoolers play a crucial role in turbocharged engines by cooling the air compressed by the turbocharger before it enters the engine. Cooler air is denser, allowing for more oxygen to enter the combustion chamber, which leads to improved power output and efficiency.
APEXi Intercoolers
The APEXi intercooler is known for its high-quality construction and efficient cooling capabilities. It features a core design that maximizes airflow while minimizing pressure drop, which is essential for maintaining performance in turbocharged applications.
Key Features of APEXi Intercoolers
- Construction: Made from lightweight aluminum for durability and reduced weight.
- Core Design: Bar and plate design that enhances cooling efficiency.
- Fitment: Direct bolt-on for easy installation with WRX models.
- Performance: Proven to lower intake temperatures significantly.
Performance Analysis
In performance tests, APEXi intercoolers have shown to maintain lower intake temperatures compared to stock units. This results in improved throttle response and power delivery, especially during extended driving sessions or under heavy load.
Grimmspeed Intercoolers
Grimmspeed has established a reputation for producing high-performance aftermarket parts, and their intercoolers are no exception. They focus on optimizing airflow and reducing pressure loss, which is crucial for turbocharged engines.
Key Features of Grimmspeed Intercoolers
- Construction: Built with high-quality materials for longevity and performance.
- Core Design: Large core size that promotes better cooling efficiency.
- Fitment: Designed for easy installation with minimal modifications.
- Performance: Effective at reducing intake temperatures, enhancing overall engine performance.
Performance Analysis
Grimmspeed intercoolers have been tested under similar conditions as the APEXi. They consistently deliver lower intake temperatures and improved power output, particularly in high-performance scenarios. Their design allows for better airflow, which is critical for maintaining engine efficiency.
Comparing APEXi and Grimmspeed Intercoolers
When comparing the APEXi and Grimmspeed intercoolers, both offer excellent cooling capabilities, but there are some differences that may influence your choice.
Cooling Efficiency
Both intercoolers provide significant cooling improvements over stock units. However, APEXi tends to excel in sustained performance under heavy loads, while Grimmspeed offers rapid cooling during quick bursts of acceleration.
Installation and Fitment
Installation for both intercoolers is relatively straightforward, with APEXi being slightly easier as it is designed for a direct fit. Grimmspeed may require minor adjustments depending on the specific WRX model.
Price Point
Pricing can vary based on the retailer, but generally, APEXi intercoolers tend to be priced slightly higher than Grimmspeed. However, the investment may be justified by the performance gains offered by APEXi.
Conclusion
Choosing between APEXi and Grimmspeed intercoolers ultimately depends on your specific needs and driving style. If you prioritize sustained performance and are willing to invest more, APEXi may be the better choice. On the other hand, if you seek a balance of performance and value, Grimmspeed is an excellent option. Both intercoolers will enhance your WRX’s performance and cooling efficiency, making them worthy upgrades for any enthusiast.
