Will these fit a 2009 subaru wrx?

Yes these will fit as i also use them in my 2009 wrx. Do not use unless you are at a minimum of 100 hp over stock though as it could hurt performance and fuel economy. These are NOT pre gapped for our Subaru WRX . Take your time and gap these plugs . Do not gap below .024 . I run a built motor and even before that i was pro tuned on both 91,93 and E85. Full bolt ons , headers, fuel pump, intake, hks blow off, blouch 20 G turbo and full 3 in back exhaust. Hybrid speed density . I still run them at .026 gap. Works very well for me.

Are these one step colder ?

Yes these are 1 heat range colder
