cold air intake, yes i'd say the AEM. lots of ppl on here have it and love it. as far as short ram, i have hypnotics short ram and i like it a lot. a good bit of other people have this as well and all seem to like it.
there are several topics that get worn out on this site.
on some other different forums i've browsed through before, not necessarily car forums, they'd practically shoot you for making new threads for topics already discussed. they'd rather you bring up an old one. i guess it depends on the moderators decision on that one.
