long life sparkplugs

have been reading some of the posts on spark plug renewal it appears that most posts i have read r&r at 30k using factory plugs my question is has no one ever tried or heard of plugs that go 100k i have them in my 4 runner (for 30k) with no issues sorry i don't recall the brand i am quite sure it was a major brand any input would be great !!

I got 240k from a set of factory dual electrode Denso copper core plugs... Platinums or Iridium are advertised to be 100k plugs or more.

 

senko here contacting you from the land of fruits and nuts thx for your reply i'll keep that in mind next time i change plugs i must say your tacoma is damn quick !!!! i would guess it is supercharged or on the bottle or possibly both ??
