any good part store, not pepboys/autozone should know exactly what you mean when you ask for 2 step cooler plugs, customcoach has intercooler piping, mandrel bends. Look around site. General discussion has his site somewhere on first page. Egay if your in no rush.

BCPR6ES-11 is stock
bcpr8es-11 is 2 steps colder
pep boys stared at me when i asked them for colder plugs...i had to give them the part number.
