perrin or amsoil, but from my speculation perrin is oiled?? amsoil is a dry filter which personally i like better

 

Actually that would be what he said unless your girl....uhhhhh.....

But enough of this off-topic crap. In all honesty OP, any filter is going to work. A filter is a filter. Sure some may filter better and others may pick up 1hp over the other but it's all the same really. K&N drop in, call it a day. Don't waste too much money on it...
