    What is the best of the "higher performance" spark plugs for my 2004 WRX ?

    Hello Fellas,

    Newbie here on this site...with that said, I am going to replace my front O2 sensor (got a P0031 DTC,CEL)
    and will also be replacing my stock spark plugs while I'm at It (got a little over 70K miles on it).

    Can you guys or gals recommend a high quality/high performace spark plugs ? Right now it looks like
    I may be looking at NGK Iridiums ( I like that they have a 100K lifespan), has anyone tried something
    like Bosch Platinum +4, Pulstar, TorqueMaster....high performance plugs for their Subbie ?

    Or should I stick to the NGK Iridiums ?


    Thanks.

    First post? Welcome to the Club!

    Stick with NGK or Denso. Platinum or iridium. I've got the NGK iridiums in my WRX.

    I'd avoid the gimmicky plugs that you mentioned: Bosch Platinum +4, Pulstar, TorqueMaster....

    Did you ever end up replacing your O2 sensor? If so do you have a link to a step by step? Or can you explain how you did it?
