Here's the deal. An easy way to check your filter is to take it out of the truck, take the filter out side, hold it up in the sun and look through the opening (the part that secures to your intake). If you can see a good amount of sunlight through the filter its ok.

Also you can do the same thing with a flashlight (this is the way I check mine). Just put the flash light inside the filter and shine the beam on various parts of the filter, exaim the outside of the filter as you do this to see how much light is escaping, the more the better. To see what I am telling you here try comparing your old filter to a new one, that will give you a night and day difference. Even though I think this is blatently obvious I'll say it anyways; when trying the flashlight "technique" make sure to do it indoors, preferably in a slightly dim room but not a dark room.

Thanks Carey! Sounds good.

I still can't believe that some of you guys change the filters every 3 months. I only drive my H2 about 7000 miles a year.
