Anyway, best bang for buck

$100 - $600 range
$100 new spark plugs (there are some good choices. Do a search on spark plugs) **
$100 K&N filter **
$575 SRT Cold Intake system & SRT Race ECU ***** (best buy, you maybe able to get one used too for around $400)

I hear lots of stickers make your car faster - something about improving your aerodynamics.
many guys have raved about the torquemaster spark plugs from the group buy offered here recently. about $110 and it'll be worth a lot more in your mind, supposedly. i'm getting them for sure.
