Great Mid Range RPM
I had a set installed in my 350z... Took a while to install but that's the fault of the engine setup of the VQ35DE not the plugs ;). Once in I noticed that the mid range RPMs felt much smoother and that my overall gas mileage seemed to improve.
 
I believe in this technology and strongly recommend these plugs.
