As far as I know, there is one and only one choice for colder STi plugs: NGK LFR-7AIX. And when I say "one and only one" I don't mean that 'cause they're great plugs, I say that because they're the *only* one step colder plugs for the STi, period.

Personally, I'd rather run a set of $4 copper plugs and change 'em frequently, but they just don't make 'em for the STi heads.
