Default Which of these NGK Iridium one-step colder plugs should I buy?

I found the part number BKR7EIX for the NGK Iridium One-step colder plugs... but then I see two variations: #2667 and #6988... I checked NGK's website but they don't list the one-step colder for the WRX.

Which is the one I need?

#2667 is the correct one colder Iridium.

The 2667 is a BKR7EIX, the 6988 is a BKR7EIX-11.

The 2667 comes with a gap of .030, the 6988 comes with a gap of .044 (1.1mm)

Don't try to gap them!!!! lol
