    How many miles on the before I should change them, seem every once in awhile my car gets really hard to start, it always does, no saying spark plugs are the problem or the fix, it just got me to wondering, I have abotu 40K on the ones in there now. I assume they are the stock plugs since the dealership put them in.

    they should be platinum so they should be good for 100k...but no harm in checking them

    Reg. Plugs for Subies are changed every 30k (recommended) and 60k for Platinums. All 02+ WRX/05+ GT/05+ XT are Platinums and the STi is Iridiums, I have to check on the STis, but I think that are 60k as well...please correct me if I'm wrong.
