Gaz Walker Posted August 4, 2006 Share Posted August 4, 2006 Rubbish! If hes got too cool a set of plugs in it will run nasty/misfire just like if they are too warm. You've got to get it just right. Is it a Supra or something else? What mods/boost is he running, what plug is he running? Gaz. Quote Link to comment Share on other sites More sharing options...

BURT Posted August 5, 2006 Share Posted August 5, 2006 i know i'm gonna get shouted for this.. but.. there is some truth in what the guy is saying.. many tuners regard these plugs as the the best, but however the tip on the the plug is very fine and can break and fall into your engine, this would be caused by bad fuelling and det etc... yes for race use i think they are gonna be great but fot the daily running of your car i would defo use NGK's they ARE AS HARD AS NAILS, and they wont tip themsevles and cost you a engine... this is just my take on this so just follow the advice you feel is best in your opinion;) Quote Link to comment Share on other sites More sharing options...
