Product Information

Full details

The Green Filters Cylindrical Breather Filter (10 x 35 x 40mm) is a specialized component designed for automotive enthusiasts and racing applications where effective crankcase ventilation is critical. Its primary benefit is preventing contaminated oil vapor from recirculating into the engine, thereby maintaining cleaner intake air and promoting engine longevity; however, users should note that this filter requires a specific vent tube diameter for secure clamping and may require periodic cleaning to maintain peak airflow.

FAQs

Does this filter fit a 15mm tube?

No, this specific model (B1.10) is designed for a 10mm connection. Please consider the B1.15 model for 15mm applications.

Can I use this on a street-legal car?

This filter is designed primarily for racing applications. Please verify your local vehicle emission regulations before modifying your crankcase ventilation system.

How often should I replace this filter?

It is a reusable filter; with proper cleaning, it can last for multiple seasons of racing.

Is it compatible with plastic breather tubes?

Yes, it is designed to clamp securely to both metal and plastic tubing of the correct diameter.

Will this filter help my engine make more power?

It helps maintain power by preventing oil vapor from fouling your intake and reducing the likelihood of detonation caused by oil mist entering the combustion chamber.

Troubleshooting

Filter keeps slipping off the tube

Ensure you are using a hose clamp to secure the filter to the 10mm tube and confirm that the tube surface is clean and free of oil residue before installation.

Filter is dripping oil

This indicates the filter is oversaturated. Remove and clean the filter, and check if your engine has excessive blow-by issues that may require a catch-can system instead of a simple breather.

Pros and Cons

Pros

  • Durable construction suitable for high-stress racing environments
  • Effectively keeps the intake tract free from oily residue
  • Simple clamping mechanism allows for fast installation
  • Lightweight and compact design

Cons

  • Requires specific 10mm tubing compatibility
  • Not suitable for closed-loop emission systems
  • May require frequent inspection in high-blow-by engines

Setup, Compatibility & Care

Installation is straightforward: ensure the engine is cool, locate the vent tube (metal or plastic) with a 10mm outer diameter, and slide the filter over the end. Use a small hose clamp to ensure the filter does not vibrate off during high-speed operation.

For care, it is recommended to inspect the filter every time you perform an oil change. If the filter media appears saturated or heavily soiled with oil, clean it using a mild detergent and water. Ensure the filter is completely dry before reinstalling it to prevent moisture from entering your engine ventilation system.
