Hi,

Time for wash & clean my KN high flow air filter, but I don't like put the special red oil in the cleaned air filter again.

What happens if I don't use these red oil?


Please, any reply,

Thanks in advance,

Denis V.

 

The oil is red because it is dyed. The oil is the real reason its called an air filter. I'm sure the thing would flow really well, but your engine to prematurely fail due to the number one cause of engine failure, dirt.

Foam air filters flow more then the cotton, but with less filtration, but the foam still uses oil.

Put the oil on like K&N says.

 

The oil just helps the filter collect the dirt and dust

 

Yeah, the "holes" through the filter media are very large on a K&N vs. a regular paper filter. The oil makes the dust stick to a fiber when it hits it instead of just bouncing off and eventually finding it's way all the way through the media and into your engine.

 

O.K., thanks,

Then...What about if I use any oil for this purpose?. For example WD-40, ATF, sae 10 motor oil, diesel oil, vegetal oil, or perhaps an italian or spanish olive oil????

WD-40 is not an oil, it is a solvent, it will evaporate in seconds with air flowing through it. The ATF and the diesel oil are too thick. The sae 10 will work. The vegetable oil, olive oil and Italian are for cooking.

Just get the oil for K&N!
