i went to the dealer yesterday to get a tune-up and out of curiousity i asked the guy what kind of plugs they used. i was surprised when he told me that they used NGK platinum plugs! i didnt know this until then, and now i'm once again impressed! :

 

Yup. stock is NGK PFR5G-11, though I have PFR6G on right now.

 

whats the difference between the two?

 

The 6's are a 'colder' heat range. They are designed for cars that do extended highway driving or that frequenntly rev into the higher engine speeds or if you have NOS (I have a story about my NOS but it will have yo wait until I get back from Maxus now, I'm about to leave and won't be back in the house).

 

hmm... gotcha. thx
