The Subaru WRX is known for its performance and rally heritage, but enthusiasts are always looking for ways to enhance its capabilities. One popular modification is the installation of an aftermarket intercooler. In this article, we will explore the real-world results of installing a Mishimoto intercooler on a Subaru WRX, specifically focusing on the performance gains we observed, which include an increase of +20 horsepower.
Understanding Intercoolers
An intercooler plays a crucial role in the performance of turbocharged engines. It cools the air that is compressed by the turbocharger before it enters the engine. Cooler air is denser, allowing for more oxygen to be packed into the combustion chamber, which can lead to increased power output. Here, we will discuss the types of intercoolers and why upgrading to a Mishimoto intercooler can be beneficial.
Types of Intercoolers
- Air-to-Air Intercoolers
- Air-to-Water Intercoolers
- Front-Mounted Intercoolers
- Top-Mounted Intercoolers
Each type of intercooler has its advantages and disadvantages. The Mishimoto intercooler is a front-mounted air-to-air design, which is known for its efficiency and ability to significantly reduce intake temperatures.
Why Choose Mishimoto?
Mishimoto is a well-respected brand in the automotive aftermarket industry, known for high-quality performance parts. Their intercoolers are designed with performance in mind, offering features that enhance both efficiency and reliability. Here are some reasons why the Mishimoto intercooler is a popular choice for Subaru WRX owners:
- High-efficiency core design
- Larger core size for improved airflow
- Durable construction with aluminum materials
- Direct fitment for easy installation
Installation Process
Installing the Mishimoto intercooler on a Subaru WRX is a straightforward process, but it requires some mechanical knowledge and tools. Here’s a step-by-step guide to the installation:
- Gather necessary tools: socket set, wrenches, and a screwdriver.
- Remove the factory intercooler: Disconnect the piping and any electrical connections.
