The Subaru WRX is a beloved vehicle among car enthusiasts for its performance and tuning potential. One of the key upgrades that many WRX owners consider is the intercooler, specifically the Perrin 22x12x3.5 Inch Intercooler. This article explores how much horsepower this intercooler can add to your WRX and what factors contribute to its performance enhancement.
Understanding Intercoolers
An intercooler is a crucial component in turbocharged engines, designed to cool the air entering the engine. Cooler air is denser, allowing for more oxygen to enter the combustion chamber, which can lead to increased power output. The Perrin intercooler is larger than the stock version, which plays a significant role in its performance benefits.
Specifications of the Perrin Intercooler
The Perrin 22x12x3.5 inch intercooler features a robust construction that enhances its cooling capabilities. Here are some key specifications:
- Core Size: 22 inches wide, 12 inches tall, 3.5 inches thick
- Material: Aluminum
- End Tank Design: Optimized for airflow
- Weight: Lightweight for easy installation
How Much Horsepower Can You Expect?
The horsepower gain from installing the Perrin intercooler can vary based on several factors, including the specific model of WRX, supporting modifications, and tuning. However, many users report an increase in horsepower ranging from 15 to 30 horsepower after installation.
Factors Affecting Horsepower Gains
Several factors can influence the actual horsepower gains you experience with the Perrin intercooler:
- Tuning: Proper tuning is essential to maximize the benefits of any performance upgrade.
- Supporting Modifications: Upgrades like a high-flow exhaust, upgraded turbo, or better fuel injectors can enhance gains.
- Ambient Temperature: Cooler outside temperatures can lead to better performance due to improved air density.
Installation Process
Installing the Perrin intercooler is a task that can be accomplished by enthusiasts with moderate mechanical skills. Here’s a general overview of the installation process:
- Remove the stock intercooler and associated piping.
- Install the Perrin intercooler using the provided hardware.
- Reconnect the intake and any necessary sensors.
