This comment right here mostly on Toyota’s and Subaru’s that’s the most I’m aware of been just rinsing my filter since. 🤝🏽💯

NO only use cold water. Hot will ruin it

NOOOO ! the reason k and n allows more air flow is because it allowed more air to pass through with bigger sized holes in filter , the oil is to help attract the dust and debris to stick to filter not passing through to your engine

the whole reason of KN is the possibility to clean it. If you want to replace every year, just buy the paper OEM filter?

@@nomad-zeni get the performance from k&n, rather than a restrictive paper air filter

Nice try paper corp

@@maliquewilliams86 What does paper corp mean? the KN lets in maybe more air but if you look close its going also let in some more dust. When I bought it and looked at it closely the pores were very large which yes lets more air in. I swapped to paper (ill clean the KN) and noticed no change in performance. While K&N filters are designed to allow more airflow than standard paper filters, the claim that they "let in more dust" is generally considered not entirely accurate; K&N filters are designed to trap dust particles through a "depth loading" mechanism, allowing them to hold more dirt than paper filters while still maintaining a high level of filtration, though some argue that in certain situations, especially with heavy dust exposure, a small amount of additional dust might pass through compared to a standard disposable filter. Key points about K&N filters and dust: Depth loading vs surface loading: Unlike standard paper filters which rely on surface loading (dust only collects on the surface), K&N filters use multiple layers of cotton fibers to trap dust throughout the filter's depth, enabling them to hold more dirt before needing cleaning. Maintenance is crucial: To maintain proper filtration, K&N filters need to be regularly cleaned and re-oiled according to manufacturer instructions. Potential concerns: Oil buildup: In some vehicles, excessive oil from the filter can contaminate mass airflow sensors. Extreme dust environments: In very dusty conditions, even with proper maintenance, a small amount of additional dust might pass through a K&N filter compared to a standard paper filter.

K&N Dryflow air filters do not use oil as part of the filtration process. When servicing these filters, you only need to use K&N Synthetic Air Filter Cleaner and water.

this is an oil free air filter.
