I'd forget the milling and pick me up one of these. http://www.knfilters.com/Racing/stubstacks.htm seen more than one guy just bolt one one with no ther mods and pick up over a 1/2 tenth. I think they were around $30 or so.



my experience with a stubstack wasn't good at all. they might work with out an air cleaner or a really tall one but for me the car wouldnt pull over 5200 rpm with a 3 inch drop base k&n filter. it seems they are really hit and miss.
