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?
