PRODUCT DETAILS

K-Series Crankcase Breather Filter – Clean Air Inlet for OEM-Style PCV Systems

Designed specifically for Honda K-series engines (K20/K24), this crankcase breather filter replaces the stock valve cover breather port fitting, allowing clean, filtered air to enter the crankcase as part of a properly functioning PCV (Positive Crankcase Ventilation) system.

Key Features:

  • Direct fit for Honda K-series valve cover breather port (16–19mm inlet diameter)
  • High-flow, washable filter media keeps dust and debris out
  • Durable, oil-resistant construction with secure clamp-on mounting
  • Maintains clean airflow into the crankcase under proper PCV function
  • Ideal for naturally aspirated, stock, or mildly modified engines

How It Works:

In a stock or properly maintained PCV system, crankcase ventilation operates on a closed-loop design. As combustion occurs, a small amount of pressure (blow-by) slips past the piston rings into the crankcase. This pressure is pulled out through the PCV valve into the intake manifold under vacuum.

To maintain airflow and pressure balance, filtered outside air must re-enter the crankcase, typically through the valve cover breather port. Our breather filter ensures this incoming air is clean and free from contaminants — protecting internal engine components and supporting efficient crankcase scavenging.

Important Note for Modified Engines:

If your engine is turbocharged, supercharged, high-compression, or experiencing excessive blow-by, this filter should not be used as a vent outlet. In those setups, crankcase pressure is often too high for the stock PCV system to handle. We strongly recommend installing an oil catch can system with proper routing to manage pressure and oil vapor safely and effectively.

Applications:

  • Honda K20 / K24 Engines
  • Naturally Aspirated or Mild Bolt-On Builds
  • OEM or Lightly Modified PCV Systems

Great product, Great price
Style: Mix, Style: Mix
I was a bit skeptical of this toy for the price especially since there were two of them. It is however it is a fantastic product, great quality and it won't deform. Perfect for medium-large dogs may be a bit too big for small dogs but if they are active then it should be fine. It makes a crinkly sound and has a small squeaker so if you want your dog to play and not make a lot of noise this is a good toy. It is soft and good for dogs to chew on so there is no risk of damaging teeth. It is easy to clean. Lastly what you see in picture is what your going to get it looks fantastic. All and all of you want a humorous to that isn't just a novelty I would highly suggest this.

Our pup loves a cold one!
Style: Mix
Our pup (dog) loves these! Something about the crinkle noise. We had gotten a four pack at Christmas and we’re needing to replace them because they had just gotten so dirty and gross even after washing them. We were so happy to find them and will definitely be purchasing some more in the near future! It’s good quality especially if it lasted 6 months for our dog! The appearance is just like the picture! And they are soft! They are perfect for our 50 pound Shepard mix dog.

May not last but worth the purchase

Furbaby loves them. I’m not sure how long they’ll last, but we will see. Giving 4 stars because the puplight squeaker doesn’t work.

Got these for my dad’s puppy. I can’t wait to see his face when he opens it on Christmas. They feel durable and have a nice noise when the pup plays with it. Absolutely love them! Extremely funny and fun for the pup:)
