Default will I get fouling with colder plug

I'm due for a spark plug change (I have an '02 WRX) and was considering getting the NGK copper plugs (# 2387 - BKR7ES-11) and was wondering if getting this colder plug would yield fouling. My car is only slightly modified:

catless uppipe
stromung turbo back (dp w/ cat)
Intercooler hoses

I do tend to drive hard frequently.

You really don't need colder plugs at your level of modification.

Realize that with copper plugs you'll need to change them about 6-10 times more often compared to iridium or platinum.
