Introduction
Ieg air oil seerator for subaru, especially turbocharged models like the WRX, STI, and Forester, are known for their impressive performance. However, these engines can suffer from oil blow-by, a common issue in turbocharged setups. The IEG Air Oil Separator (AOS) is an essential upgrade for Subaru owners who want to protect their engines and improve performance. In this guide, we’ll dive into what the IEG AOS is, its benefits, and why it’s so important for Subaru engines.
What is an Air Oil Separator?
The Function of an Air Oil Separator
An air oil separator (AOS) is a device installed in a vehicle’s engine system that separates oil from the air that’s recirculated through the engine. In turbocharged engines, like those found in Subaru WRX and STI models, oil blow-by occurs when small amounts of oil escape the engine and mix with the air in the intake system. Over time, this can lead to oil buildup in the intake, which affects engine performance and can cause long-term damage.
How Air Oil Separators Work in Turbocharged Engines
The IEG AOS works by capturing the oil vapors before they enter the engine’s intake system, separating the oil from the air, and returning the clean air to the intake while routing the oil back to the engine. This process ensures that the air circulating in the system is clean, preventing oil buildup and reducing the risk of engine damage.
Benefits of Installing an IEG Air Oil Separator for Subaru
Prevents Oil Contamination
One of the primary benefits of installing an IEG Air Oil Separator is the prevention of oil contamination in your engine’s intake system.
Reduces Engine Knock
Oil blow-by can cause an issue known as engine knock, where the air-fuel mixture in the engine’s cylinders ignites prematurely. This knocking can lead to serious engine damage if left unchecked. By keeping oil out of the intake system, the IEG AOS helps reduce the likelihood of engine knock.
Improves Performance and Longevity
With cleaner air entering the engine, your Subaru’s performance improves. Over time, this can lead to better fuel efficiency, more consistent power output, and a longer engine lifespan.
Why Subaru Owners Need an IEG Air Oil Separator
Common Oil Problems in Subaru Engines
Subaru’s turbocharged engines are prone to oil blow. Without an air oil separator, oil can accumulate in the intake system, leading to carbon buildup, reduced performance, and potential engine damage.
How the IEG AOS Addresses These Issues
The IEG Air Oil Separator is specifically designed to combat these oil-related issues. By efficiently separating oil from the air and preventing it from entering the intake, the AOS reduces the risk of engine problems and helps maintain optimal performance. This makes it a highly recommended upgrade for Subaru owners who want to protect their investment.
Different Types of IEG Air Oil Separators
IEG Competition Series AOS
The IEG Competition Series AOS is designed for high-performance. It offers superior oil separation capabilities, making it ideal for Subaru owners who push their cars to the limit.
IEG Street Series AOS
For daily drivers or lightly modified Subaru models, the IEG Street Series AOS is a perfect choice. It’s easier to install and requires less maintenance compared to the Competition Series.
Choosing the Right AOS for Your Subaru
When choosing an AOS, consider how you use your Subaru. For daily driving, the Street Series is more than sufficient to protect your engine from oil blow-by.
Installation of the IEG Air Oil Separator
Step-by-Step Installation Guide
Installing an IEG Air Oil Separator is a straightforward process, but it does require some mechanical knowledge. Here’s a basic overview:
- Locate the Installation Area: Typically near the engine bay or firewall.
- Disconnect the Intake and PCV System: Carefully remove any hoses and components that will interfere with the installation.
- Mount the AOS Unit: Using the provided brackets, secure the AOS in the designated area.
Tools Required for Installation
- Basic socket set
- Screwdrivers
- Hose clamps
- Pliers
Common Installation Mistakes to Avoid
- Improper hose routing: Ensure that hoses are properly routed.
- Loose fittings: Double-check that all connections are tight to prevent leaks.
Maintenance and Care for the IEG Air Oil Separator
How to Maintain Your AOS for Optimal Performance
While the ieg air oil seerator for subaru is relatively maintenance-free, occasional checks are recommended. Ensure that the hoses are intact and there are no leaks around the fittings.
Signs Your AOS Needs Servicing
- Oil leakage around the AOS unit
- Reduced engine performance or increased oil consumption
- Unusual engine noises or knocking
Conclusion
The ieg air oil seerator for subaru is a must-have upgrade for Subaru owners who want to protect their engine from the harmful effects of oil blow-by. Whether you’re driving a daily Subaru or pushing it to the limits on the track, the AOS provides essential protection, improves performance, and extends the life of your engine. Make sure to choose the right model for your needs and follow proper installation and maintenance procedures to ensure optimal results.
