I'm inquiring what plug gap people are running after installing the MSD wasted spark board and coil? I was under the impression that we open the gap, (.75mm standard) but inquiring to the techs at MSD they told me .65mm on Denso IK27 Iridium?

 

..Be carefull with denso ik..i lost a tip on one...i am afraid now to use them but lots do without any issues..i would just fitted them without adjusting....
