I have 1 bad injector so if im going to go through all the trouble to remove the plenum i might as well replace all of them. I'm going to stay stock 370cc. What are some good ones and bad ones? or is stock OEM the way to go? I realize cheap does not exist but not break the bank. Also with injectors is it swap them and good to go or do new o rings, gaskets etc need to be replaced as well? This is a new area in my knowledge
