I got a 2000 jetta glx with around 76k on the stock motor and was wondering what are the best mods that are out there where i can get the best hp gains

 

you never great HP gains without first spending big money, cams and internal motor work is where the great gains are. In the meantime stick to bolts ons, exhaust, air intakes, performance chips, mine was $400-something and it's from APR, look on eurotuneracc.com, or get yourself a eurotuner mag..it helps I have the same motor, it's tough, just gotta know where to look.
