Thank you for the reply. Now, what does "G" power mean? I have seen a handful of "whatever letter" powers. What is the difference in the powers? It seems like I have even seen the same part number, LZFR5C-11, with the different lettered powers. Wouldn't different rated spark plugs have different part numbers?
