ko3

  1. VW Jetta / Bora MKIV 1998 Euro,1999.5 US -2005
    something came into my head today...what if i added another ko3 to my 1.8t? obviously i would have to chip..but would twin ko3's make any sence? would it work? would i get a significant horsepower gain? what would i have to do to make it work(if it would)? theres a junkyard nearby my home that...
