When it comes to performance upgrades for the G87 M2, aftermarket intercoolers have become a popular topic of discussion among enthusiasts. One of the most frequently debated questions is whether these upgrades are truly worth the investment. In this article, we will explore the differences between the stock intercooler and the Wagner EVO 2 intercooler, examining their performance impacts, installation processes, and overall value.
Understanding Intercoolers
Intercoolers play a crucial role in a vehicle’s performance by cooling the air that enters the engine. Cooler air is denser, allowing for more oxygen to be packed into the combustion chamber, which can lead to increased power and efficiency. There are two main types of intercoolers: air-to-air and air-to-water. The G87 M2 utilizes an air-to-air intercooler, which is the focus of our comparison.
Stock Intercooler Overview
The stock intercooler in the G87 M2 is designed to meet the performance needs of most drivers. It provides adequate cooling for daily driving and moderate performance applications. However, for those looking to push their vehicle to higher performance levels, the stock intercooler may not suffice.
Specifications
- Core Size: Standard dimensions
- Material: Aluminum
- Cooling Efficiency: Adequate for stock power levels
Wagner EVO 2 Intercooler Overview
The Wagner EVO 2 intercooler is an aftermarket upgrade designed to enhance performance significantly. It features a larger core and improved airflow characteristics, which can lead to better cooling efficiency and overall engine performance.
Specifications
- Core Size: Larger than stock
- Material: High-quality aluminum
- Cooling Efficiency: Enhanced for high-performance applications
Performance Testing
To determine whether the Wagner EVO 2 intercooler is worth the investment, we conducted a series of performance tests comparing it to the stock intercooler. The tests measured temperature drop, boost pressure retention, and overall power output.
Temperature Drop
One of the critical metrics for evaluating intercooler performance is the temperature drop achieved during operation. The Wagner EVO 2 showed a significant reduction in intake air temperatures compared to the stock intercooler, particularly during extended high-performance driving.
Boost Pressure Retention
Another important factor is how well the intercooler retains boost pressure. The Wagner EVO 2 maintained boost levels more effectively than the stock intercooler, leading to improved throttle response and acceleration.
Power Output
Finally, we measured the power output of the G87 M2 with both intercoolers. The Wagner EVO 2 provided a noticeable increase in horsepower and torque, particularly at higher RPMs, making it a compelling choice for performance enthusiasts.
Installation Process
Installing an aftermarket intercooler can vary in complexity. The Wagner EVO 2 intercooler is designed to fit the G87 M2 with minimal modifications, but it still requires some mechanical knowledge and tools.
Steps for Installation
- Remove the front bumper
- Disconnect the stock intercooler
- Install the Wagner EVO 2 intercooler
- Reconnect all hoses and sensors
- Reattach the front bumper
Cost Consideration
When evaluating whether aftermarket intercoolers are worth it, cost is a significant factor. The Wagner EVO 2 typically retails for a higher price than the stock unit, but the performance gains can justify the investment for serious enthusiasts.
Conclusion
In conclusion, if you’re looking to enhance the performance of your G87 M2, the Wagner EVO 2 intercooler is a worthy investment. Its superior cooling efficiency, boost pressure retention, and power output make it a valuable upgrade over the stock intercooler. For those who prioritize performance, the benefits of the Wagner EVO 2 far outweigh the costs.
