Advanced Features and Specifications

The COBB Air/Oil Separator utilizes a drain-back system that not only cleans your engine's valves but also reduces the likelihood of detonation by removing oil particles from the PCV gases. This results in a cleaner, stronger engine capable of delivering more power with reduced maintenance. The separator is designed to install in series with the original PCV circuit, forcing air through a swirl pot and baffles to promote condensation and collection of oil particles. This drain line then returns the condensed oil to the crankcase, ensuring that your engine operates efficiently.
  • Drain-back system for cleaner valves and reduced detonation
  • Engineered to install in series with the original PCV circuit
  • Optimized swirl pot and baffles for efficient oil particle collection

Practical Benefits and Target Audience

Whether you're a performance enthusiast or a daily driver, the Cobb Tuning Air/Oil Separator offers significant benefits for your Ford Focus ST. By preventing crankcase oil vapors from recirculating into the intake system, this separator enhances engine performance, improves fuel efficiency, and extends the life of your engine. This kit is ideal for anyone looking to maximize the potential of their Focus ST while ensuring minimal maintenance and risk.
  • Enhanced engine performance and fuel efficiency
  • Extended engine life and reduced maintenance
  • Perfect for both performance enthusiasts and daily drivers
