That is neat....
The 370z / R 35 coilpacks nearly straight bolt up. I just cut the taper at the boot and the height is nearly identical. Switch a few wires and you have a direct on coil ignition with R35 spark.... and they are cheap.
Video is of 350, but 370z's are nearly identical and should be the same part number as R35..... I think it is the strongest spark amongst coilpacks?
