TurboGS300 Posted January 26, 2004 Share Posted January 26, 2004 I just added the NGK Iridiums and new plug wires to my 93 gs300! I also cleaned a bunch of black gunk off the back side of the throttle body and intake manifold, made a big difference in idle. Quote Link to comment Share on other sites More sharing options...
alexus Posted January 28, 2004 Share Posted January 28, 2004 i wanted to put 'em in my car.. are they good? Quote Link to comment Share on other sites More sharing options...
TurboGS300 Posted January 29, 2004 Author Share Posted January 29, 2004 They are a better plug period, but as far as noticing any gains, I can't really say that I have in the lexus. I put them in my Mazda MX6 and I swear it seems a little faster! I would put them in just because they are the best plug out right now! :D Quote Link to comment Share on other sites More sharing options...
