Apexi Super Intercooler Vsstock: Which Boosts Power More on Your Wrx?

The performance of your WRX can be significantly enhanced by upgrading the intercooler. In this article, we will compare the APEXi Super Intercooler with the stock intercooler to determine which one provides a greater boost in power.

Understanding Intercoolers

Intercoolers play a crucial role in the performance of turbocharged engines. They cool the air entering the engine, which increases density and allows for more air to be packed into the combustion chamber. This results in better combustion and more power.

APEXi Super Intercooler Overview

The APEXi Super Intercooler is designed specifically for performance enthusiasts looking to maximize the efficiency of their turbocharged engines. Here are some key features:

  • Core Design: The APEXi intercooler features a larger core that increases surface area for better heat dissipation.
  • Construction: Made from high-quality aluminum, it is lightweight yet durable.
  • Flow Efficiency: The design promotes optimal airflow, reducing pressure drop.

Stock Intercooler Overview

The stock intercooler that comes with the WRX is adequate for everyday driving and moderate performance. Here are its main characteristics:

  • Core Size: The stock intercooler has a smaller core compared to aftermarket options.
  • Material: Typically made from plastic and aluminum, it is less efficient at cooling.
  • Heat Soak: Under high-performance conditions, the stock intercooler can suffer from heat soak, reducing its effectiveness.

Performance Comparison

When comparing the APEXi Super Intercooler to the stock intercooler, several performance metrics can be evaluated:

  • Cooling Efficiency: The APEXi intercooler provides superior cooling, allowing for more aggressive tuning and higher boost levels.
  • Power Gains: Users have reported noticeable power increases with the APEXi intercooler, often in the range of 15-30 horsepower.
  • Response Time: The APEXi intercooler improves throttle response due to better airflow.

Installation Process

Installing an aftermarket intercooler can be a straightforward process for those with mechanical skills. Here’s a brief overview of the installation steps:

  • Remove the stock intercooler by disconnecting the piping and mounting points.
  • Install the APEXi intercooler, ensuring all connections are secure.
  • Reattach the piping and check for any leaks before starting the engine.

Cost Considerations

When deciding between the APEXi Super Intercooler and the stock option, cost is a significant factor. Here’s a breakdown:
