I have a Ford Motorsport chrome air cleaner - 13" OD and I can't find anyone that has a 13" filter but K&N. The problem with K&N is that the only 13" filter they have is 6" tall, and it'll probably cause a little clearance problem with my hood (cutting a hole in my hood isn't an option, so don't go there lol). I was shooting for a 4-5" tall filter but I can't find anybody that offers them in a 13" OD. Does anybody know where I can find one?
And is there really a performance benefit in a 6" tall filter? I've heard of guys stacking two of the same filter on top of each-other but I thought it was only for looks.
