i think the renix works as much because it's a step colder than
because of its reach.  iirc folks have had a hard time finding other
than stock plugs for the 4.0.

if you're running lean you should definitely be able to run a colder
plug.  one of the standard reasons for a hotter one is to burn off
the deposits created by short around-town-driving trips.  on top of
that, gas now probably doesn't leave the crud it used to.
