well trailing or top plugs are 9s stock and those are the colder plugs
so im guessing the 11 would be the trailing since it is colder than 10. Most guys run the trailing plug for all 4. I use all stock trailing plugs bur9eq I dont think you need a set of plugs like that unless you have a ton of hp like 550
I could be all wrong however.

How modified is your car? Running plugs in that range on a relatively stock car on the street is going to fowl them in a hurry.

The plugs will be done in a hurry or the plugs will fowl the engine.??
