ATV's come standard with Foam Air Filters. If you have a K&N air filter, check out how to Clean K&N Air Filter.

No matter where you ride, how you ride or how long you ride, the air filter will always get dirty. So regularly check your air filter, especially if you ride your ATV with an open airlid.
I have to say, I clean my air filter after each ride and never had to replace it ever, nor did I ever have engine damage caused by a dirty filter.

How to grease in the air filter?

An air filter doesn't only need cleaning, it also needs to be greased in with Filter Oil to prevent tinny particals of dust to penetrate the air filter.

Using (blue) Filter Oil you can grease in the air filter. You can also use motoroil. But don't let anyone fool you you can also do it with sunflower oil or any other type of oil.

- Put on some rubber gloves and evenly rub in the Filter Oil.

TIP: Another easy way to manage this without gloves is by taking a plastic grocery bag, put the air filter in together with some Filter Oil, close up the bag and give it a good massage. No need for gloves then.

 

- Next, make sure you DON'T LEAVE the air filter extremely GREASY to ensure a good airflow! Take some kitchen paper or a newspaper and roll the air filter in it. Squeeze out and rub off as much redundant grease as possible.

- Put the air filter back in your (cleaned) airbox and let it dry for about 24 hours to ensure maximum airflow.


Now we're talking about a highly maintained and clean foam air filter!
