Chuy Posted May 29, 2012 Share Posted May 29, 2012 Has anyone changed theirs? What brand are OEM? What did you get? Any issues installing them? Mine are overdue. I'm considering NGK Iridium IX. Quote Link to comment Share on other sites More sharing options...
lenore Posted May 29, 2012 Share Posted May 29, 2012 Stick with OEM Denso, or NGK iridium plugs...They are good for 125k miles......THe rear three will be a challenge. Quote Link to comment Share on other sites More sharing options...
Lexusfreak Posted June 7, 2012 Share Posted June 7, 2012 As lenore mentioned...nothing but OEM plugs which will be either NGK or Denso (Iridiums...which are different & than the IX plugs which won't last nearly as long). Quote Link to comment Share on other sites More sharing options...
