Not true.
DENSO sells two types of iridium plugs;

IK16 is the "regular" Iridium plug you're writing of.

SK16R11 is the "long life" Iridium OEM replacement part they market that the dealer sold me.

Wrong answer. ik16 is the iridium "POWER" plug and the one you want.
The ik16tt is the standard iridium.
The sk16r11 is the iridium long life.
