Hey guys i just got my k&n panel filter yesterday and when i put it in i noticed there is like another filter in the lid of the stock airbox? does anyone know what this is and how to remove it seems like it would just defeat the purpose of the k&n. i tried prying it out but it wouldn't budge do you have to break it to get it out? and if you take it out will it hurt anything? (ie check engine lights, ect.) thanks in advance!
