You can get either from sparkplugs.com Quote Link to comment Share on other sites More sharing options...
jcrome04 Posted February 14, 2008 Share Posted February 14, 2008 I got NGK G-power platinums :( Is this ok? I thought the 1UZFE recommended platinums? Quote Link to comment Share on other sites More sharing options...

jcrome04 Posted February 14, 2008 Share Posted February 14, 2008 Is there a big difference between the OE platinums and NGK G-Power Platinums?? Quote Link to comment Share on other sites More sharing options...
SRK Posted February 14, 2008 Share Posted February 14, 2008 Is there a big difference between the OE platinums and NGK G-Power Platinums?? No. Either Denso or NGK plugs are so close to stock part numbers it doesn't matter. Quote Link to comment Share on other sites More sharing options...
jcrome04 Posted February 14, 2008 Share Posted February 14, 2008 Ok phew! :D Now I don't feel like an idiot anymore! hahaha Quote Link to comment Share on other sites More sharing options...
nc211 Posted February 14, 2008 Share Posted February 14, 2008 Ok phew! :D Now I don't feel like an idiot anymore! hahaha wait for a vibration problem....trust me, the LS400 has the ability stump Einstein with it comes to figuring out what in the heck is causing the vibration. But, that's what we're here for! ;) Quote Link to comment Share on other sites More sharing options...
jcrome04 Posted February 14, 2008 Share Posted February 14, 2008 There will be a vibration problem with anything other than OEM plugs?????? Quote Link to comment Share on other sites More sharing options...
nc211 Posted February 14, 2008 Share Posted February 14, 2008 There will be a vibration problem with anything other than OEM plugs?????? Hahaha.... not that I'm aware of! I"m talking in general, when a wheel goes out of balance, or a warped rotor in the back, etc... the car is so smooth to begin with, that when something small like that happens, you know it, and instantly think it's something major. You weren't around here when I use to have my signature being the list of parts I had replaced, chasing vibrations... It was the classic overkill signature. But Citibank loved it!
