confused about NGK part #
NGK plugs in my jdm itr motor read PFR7G-11. The helms factory manual says to use PFR6G-11. and the deal sold me PFR5G-11. What the hell is the differences in the 7G, 6G, 5G. Is the 7G the best and the 5G the worst??

Heat range is dictated by that first number.
7 is colder than 6.
5 is hotter than 6.
The 7 heat range is a JDM B18C thing.
USDM B18C5's came with the 6 heat range plugs.
Get the heat range 7's.
