Folks in the MK7 community are always talking about the idle...I've never really noticed any difference between any of the plugs that wasn't just placebo/in my head. I did think these may idle a little rougher but then other times smooth...just like all the plugs I've done. I did think that Ruth's were super smooth but of course without actual data (vibration, idle RPM variation, etc.) this is completely meaningless.
We all work for the same company. Some engineers only work on APR products. Some only work on LS swaps. Some are shared across various buildings and locations. Really depends who is the expert on the subject.
