after putting in my new ic and heat shield i think i'm going to switch my hks filters out for two k&n's but i'm having a hell of a time tracking down the specific number of the filters needed. Can anyone help me out with this?

they make a lot. the best thing to do is to take your measurements and go to their website.

Have you checked out Simota air filters ?

some say better than K & N and slightly less expensive

I just checked out simota but i'm looking for the cylindrical filters to attach to the aluminum hardpipes and they don't really have anything that will do that.

Joe,
Double check the demensions of those pipes, but I think you want RD-0720 (2.5 inch straight flange). I've also seen some with a slight angle on primary to keep it from interfering with the upper secondary. That one would be RB-0720.

RB-0720 is probably the most common K&N for an FD.
