does anybody know, or recommend anything to boost up engine horsepower on 1.8t engine?

are there any fog lights that fight the 2004 jetta's front air intakes?

better breathing might help

1.8T's are verryy easy to mod. a chip will get you a ton oh HP. there is another thread on here somewhere about it. upsolute chips are around 300 bucks, APR's are around 600 IIRC. switching out your dowpipe will also give you some added power. get a downpipe before a catback because you will notice more gains with the dp. cold air intakes can be had pretty cheap and may give you a few ponies.
