thinking of running denso iridium IK20s instead of the NGK PFR7Q OEMs.

anyone running iridiums?

in principle, the double platinums and iridiums should have similar conductivity.

the electrodes are also of the same shape.

i'm guessing it'll work, but wanted to see if anyone here was already running iridiums
