I saw those on Ebay they werent NGK or Denso, they were a knock off called IX's or something like that.mitsu3kgt311 said:ha ha ha, i saw those on ebay, the guy wanted $75 for 6, and he said they were dyno tested on a 1.8L civic, and it gained 60HP!!! then he said they would add 21HP on a 3000GT!!
first of all, how would spark plugs add 60HP on any car? and second, how would they add more power on a civic over a 3000GT?
i just thought that was funny, but yeah i hear the denso plugs are good & so are the NGKs...
1 range colder than stock, unless you are planning on running 20+ psi, in which case 2 ranges colderDrewVR4 said:I have Denso iridium plugs and I am having my motor rebuilt with upgraded turbos and fuel system, what heat range should I be using?
