injectors
 

are all the 440 injecters the same from 92-00 classics

no the later ones need a adapter kit to fit your fuel rails, i also heard that the version 3 sti yellows were actually 420ccs not 440ccs, but have no evidence to prove this true.

where do i get the adaptor kit and how much. and are they any good
