intake for wrx
unless you're going to get a fmic that requires a short ram kit, stick with the stock airbox. with aftermarket intakes, you'll get flow inconsistencies due to maf misreadings and what results are unstable a/f ratios. i've seen this firsthand with the greddy airinx on my car when i went to have it dyno tuned. i could have made more reliable power off of the stock airbox cause i could have safely ran a leaner map. i still have the greddy in cause i'm about to install a r-spl fmic.

good and cheap intake mod:
higher flowing panel filter (ex. k&n) - $40 -$60
remove silencer
take out air scoop
replace hole with fender blocking plate (from OEM '99 impreza i believe)-$3.00
seal airbox to fender with foam weatherseal - $2 or $3
-looks great, faster spool up,and you can hear bypass valve and sucking sound from turbo!

I am in the process...
I'll post back in a day or two... My cars at the dealer getting the clutch fixed... soon as I get it back I'll be taking out the silencer and the snorkel and sealing things up. Apparently this is really common.
