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

Necessary for travel
Size: Medium (6.8"W*4.4"D*2.2"H), Color: Purple
This is really cute and looks classy. Quality is very nice. The only thing is the hooks for the necklaces didn’t keep them on, but everything else about this is a must for traveling and not losing or tangling up your jewelry.

LOVE IT!
Size: Large (8.2"W*4.2"D*2.4"H), Color: Beige
I love it. It’s very pretty and simple, in a good way. I plan to use it for all my jewelry and not just for travel. I like that it has a lot of hooks for necklaces and plenty of space for earring and rings. The fabric inside and out seem to be good quality. It’s well made and zips easily. The structure is sturdy as well. The color (white) is just as depicted. I think I got the larger size but it doesn’t feel bulky at all. I like that it comes with an extra pouch for bulkier items. It’s one of the best jewelry boxes I’ve had!

Nice little travel solution for jewelry
Size: Medium (6.8"W*4.4"D*2.2"H), Color: Pink
Cute travel box for my jewelry. The necklace hangers aren’t all that snug, causing my necklaces to fall and tangle some. But otherwise, works as expected.
