anyone know what size intake do i get for an injen intake..

i bought the car with an intake already on it.. and dont know size of filter..

anyone have any experience.. my filter is somewhat old and dirty and i need to change it..

also can i remove filter from the driver side fender liner?

 

do you know what version is your intake?? because the old version of injen intake are thinner and the newer is thicker

 

what do you mean thinker and thinner.. isnt intake filters interchangeable? i just need to know what size outlet it is.. like 3 inch? im clueless.
