I'm assuming you are talking about the IFR6T11 when you say OE plugs, NGK's website has them listed as "OE Laser Iridium."
I felt that the 4Runner deserved a treat for being such an awesome truck, so Imma splurge on new plugs. Just wanna make sure that they are worth it. I have never had a problem with NGK, they are one of the top manufactuers in my book.
