I like the DENSO iridiums
ITV22 is the stock SVTF Plug
ITV24 is 1 step colder than SVTF
ITV27 is 2 steps colder than SVTF
I'm running the ITV27's right now, on the stock plugs I had some issues under boost and high rpms, these ones don't have these issues. 30,000km's and going strong. I think when I swap them out i'll just go with ITV24 I suspect i'll probably get a better burn from these plugs.
Also check check check your timing belt....
