Vented loops are commonly used in the marine toilet system and engine cooling system. The simple valve system incorporated in the top of the loop allows air to enter the line when not in use, yet effectively seals as water or other fluid passes through. Molded in Marelon, neither vent nor loop will corrode. The duckbill one way valve

Good deal
Size: CF10930&16546AA090
Seems a bit thinner than my last two, but they did come together for the price of one. Seems to be of good quality non the less. Fits well in my 2014 Subaru forester

Perfect fit for 2025 Honda CR-V Hybrid Sport
Size: 2023-26 CRV 2.0L Hybrid
This filter pack was a perfect fit when needing to replace the cabin and engine filter for my 2025 CR-V Hybrid. My Honda dealer wanted $140 ($70 ea.) to replace both filters while this pack only cost $30. The cabin filter was a piece of cake, but the engine filter took a bit of an effort. Nothing too crazy, though. Definitely worth the money.
