Denso iridium plugs
 
Has anybody run Denso iridium plugs (IKH16)? They claim they are long lasting.

I know that the 2009 - 2012 5.7L HEMI does not like IRIDIUM plugs

NGK makes the plugs that are in the Parts Dept.
NGK Standard LZFR5C-11
Laser Platinum PLZFR5B13EG * ( the platinums have been know to melt the coils )

OR

Champion REC14MCC4 and gap to .040" (1 mm) every 30.000 miles (50.000 km).
