I have a Mazda3, and planning boost for the 2.3L (12 psi max to be exact)

one the parts needed on the list would be colder spark plugs, after some search, I cannot find a solid part number to which people are using for NGK plugs that are one step colder..

the only one I found so far is

NGK LTR7IX-11

how about the part number for one step colder copper plugs??? or any other NGK part #'s or other brand's in which are one step colder then stock????

thanks for your help
