Oiled Filters. … Generally, high-performance dry filters can catch up to 99% of the incoming contaminants due to the smaller micron size of the filter media, while oiled filters catch about 98% of what passes through – a minute difference, but a difference none-the-less. Big vs small!
What happens if you don’t oil your K&N filter?
K&N filter elements have larger holes than stock air filters to allow more air through. The trade off is that without the oil, those larger holes would let in more dust type particles which, as anyone who knows engines will tell you, is not good for the engine.
Can you use wd40 as air filter oil?
