2015-2021 Subaru WRX Baffled Oil Catch Can PCV Side

The WRX Catch Can is designed to capture excess oil and contaminants that escape past the piston seals into the crankcase. In Subaru WRX engines, blow-by is common, especially with direct injection systems, leading to carbon buildup on intake valves. By capturing oil vapors before they reach the intake, the WRX Catch Can helps prevent carbon deposits, protecting performance and enhancing engine longevity.

Oil vapor escapes during combustion, but the WRX Catch Can intercepts this blow-by, ensuring cleaner airflow and preventing contaminants from re-entering the intake. This leads to improved combustion, better throttle response, and overall engine efficiency.

Specifications: 

• Installs in under 30 minutes

Features：

• Carbon Buildup Prevention: Oil catch cans capture oil vapors and contaminants before they reach the intake, preventing carbon deposits on valves and maintaining engine efficiency.
• Improved Airflow: By keeping the intake system clean, oil catch cans ensure smooth airflow, leading to better combustion and throttle response.
  
• Enhanced Performance: With reduced carbon buildup, the engine operates more efficiently, boosting horsepower and torque for a more powerful driving experience.
  
• Reduced Engine Knock: Oil catch cans prevent oil vapor from causing pre-ignition or engine knock, protecting the engine from potential damage.
  Extended Engine Lifespan: By reducing contaminants, oil catch cans help minimize wear on critical engine components, extend engine life, and reduce maintenance costs.

Are WRX Catch Cans bad for your car?

No, WRX Catch Cans are beneficial, especially for direct injection engines like those in the 2015-2021 Subaru WRX. They prevent oil and contaminants from building up in the intake manifold, keeping the engine clean, reducing carbon buildup, and maintaining performance.

How Does a WRX Catch Can Work?

The WRX Catch Can captures oil vapors and contaminants before they reach the engine’s intake. Connected to the engine’s ventilation system, it slows and redirects gases, allowing oil particles to condense and collect at the bottom. This prevents oil from re-entering the intake, helping reduce carbon buildup, improve airflow, and protect engine performance, ultimately extending engine life.

For 2015-2021 Subaru WRX owners, oil blow-by can cause carbon build-up on intake valves, leading to reduced engine performance and potential long-term damage. The Flashark Baffled Oil Catch Can PCV Side effectively captures oil vapors before they reach the intake, keeping the engine clean and enhancing throttle response, overall performance, and engine longevity.
