(The only correct one on that list is the Denso IR.)
Other than that, most oem plugs are going to be PT or IR, simply because they are superior to conventional plugs. (9G OEM plug is IR) Now the true factory plugs are going to be expensive, but imho that shouldn't be a problem when you can buy the NGK Iridium IX plugs for around $7 a pop at any Advance Auto. Also, it's been said a million times but here it is again: only use NGK or Denso, nothing else.
