I own a 97' legacy GT with over 100 k on it. I love the car (except my heat sheild rattels, but I already got some good advice from another thread). I am looking for some simpel mods to increase performance in the mountains (I live in Denver). I'm not to tech. orientated. I have considerd some of the fancyer intakes but have also heard that the oil on the filter can get in your motor. Anyone have suggestions on this or other mods, possably even a turbo/super charger.
