Lets say you have a stock raptor. What are the choices of air filters? I know there are aluminum filters waht do they do? if i dont use a lid do i need a breather filter thingy? ????

 

Any body? I need helppppp??????

 

Theres lots of choices for filter and airbox options. I run no airbox with dual K&N's coming off sixsixt's adapter plate and couldnt be happier. I only ride sand however. I suggest u get a k&n and take the lid off and jet up. Thats if your not running in muddy or alot of water conditions.
