The Radium Engineering 20-0607 Air Oil Separator-Return Kit is a high-performance upgrade designed specifically for the 2015 Subaru STI. This kit replaces the original factory air oil separator and returns system, enhancing the engine's breathability and reducing unwanted engine emissions.
The heart of this kit is a high-flow, reusable, and larger capacity baffled aluminum air-oil separator. This separator is designed to efficiently remove water and contaminants from the crankcase ventilation system before they enter the intake, ensuring a cleaner and more efficient combustion process. A larger baffle plate in the separator increases the overall capacity, allowing for longer intervals between dragging and subsequent maintenance. This component is also CNC machined for precision and boasts a polished and anodized finish for a distinctive and long-lasting look.
The kit also includes all necessary hardware, hoses, and brackets for a straightforward and hassle-free installation process. The kit's hoses are specifically engineered with a high-temperature and oil-resistant material to withstand the rigors of rally and high-performance driving. Additionally, the high-quality hose clamps ensure a secure and leak-free connection.
The return kit is designed to integrate seamlessly with the factory coolant system, utilizing the original coolant temperature sensor. This eliminates the need for additional wiring and modifications, simplifying the installation process and maintaining a stock-like appearance.
In summary, the Radium Engineering 20-0607 Air Oil Separator-Return Kit offers improved engine performance and enhanced durability for 2015 Subaru STI owners. Its high-flow design, superior materials, and seamless integration make this upgrade a must-have for those seeking optimum performance from their vehicle.
The Radium Engineering 20-0607 Air Oil Separator-Return Kit is a popular upgrade for the 2015 Subaru STI. This aftermarket modification aims to improve the performance and longevity of the engine by separating engine oil mist from the crankcase vent gases before they enter the intake system. Here's a balanced evaluation of this product.
Pros:1. Improved Engine Performance: The seperator-return system helps maintain cleaner intake charges and reduces oil in the intake, leading to enhanced engine performance.
2. Longer Engine Life: The separation of oil vapors and mists from the crankcase gases keeps the intake system clean, which can lead to reduced wear and tear, thus contributing to a longer engine life.
3. Better Fuel Economy: As the engine operates more efficiently due to cleaner intake charges, the overall fuel economy of the vehicle could potentially improve.
4. Reduced CEL and Check Engine Light: By preventing excessive oil deposits in the intake system, this kit might help reduce the chances of the Check Engine Light coming on.
5. Compatibility: The Radium Engineering 20-0607 kit is specifically designed for the 2015 Subaru STI, offering assurance of a perfect fit.
Cons:1. Cost: The kit can be considered an expensive upgrade for some enthusiasts, especially those looking for performance improvements on a tight budget.
2. Installation Complexity: The installation process is not as straightforward as some other bolt-on parts, requiring modification of the factory air intake hose tail, making it potentially more time-consuming and labor-intensive.
3. Maintenance: While the primary advantage of the kit is its maintenance benefits for the engine, it also requires occasional maintenance, such as changing the separator oil and filter.
4. Loudness: Some users have reported that the kit creates a noise, particularly when starting the engine or during cheap gas transitions.
Conclusion:The Radium Engineering 20-0607 Air Oil Separator-Return Kit offers potential benefits for Subaru STI owners, including better engine performance, longer engine life, potential fuel economy gains, and reduced Check Engine Light occurrences. However, its relatively high cost, installation complexity, maintenance requirements, and possible noise generation are valid considerations. Ultimately, the decision of whether to invest in this kit depends on individual preferences and priorities.
Recommendation:If you're an enthusiast with a focus on engine performance, a long-term Subaru STI owner, or someone concerned about the potential harmful effects of engine oil mist on their vehicle's intake system, the Radium Engineering 20-0607 Air Oil Separator-Return Kit could be a valuable investment for you. However, if the cost, complexity, and potential noise generation outweigh the benefits for your specific situation, it might be worth considering alternative methods to maintain engine cleanliness and performance.
