i had an HKS intake filter on my 91 240. i was pleased w/ it. when i installed it, i noticed a small gain after 4500 rpms. but it was on stock plastic piping. i think i'm going to stick w/ jdm filters, but my friend and i are about to try and creat our own piping. at first i didn't understand the point of even getting piping, but it just hit me when i was reading this thread (cold air vs hot air).
JDM filters on stock piping is "ok". you'll notice a "meaner" sound from ur engine, and lil power gain. if nething, its just a better throttle response (like piping would give you a whole lot of HP ne way).
