If I remember correctly NGK's numbers go down with higher heat
so if the stock plug is a BPR6ES-11 Just get a BPR5ES-11. Some stores like mine don't use the long numbers though, so give me a holler and I'll give you the four digit stock number.

You are correct about the numbers of the NGK plugs. A lower number is a hotter plug. Your glove box manual should specify the correct NGK plugs for your car.
