I ordered that tuneup kit from that one website, and I compared the new spark plugs to the old, and I noticed they had different numbers. The old is PFR5G and the new is BKR5E. Are they the same thing?

 

i always thought the P was for platinum.. but matt is running those new plus you have and he doesn't run plat.. BKR7E just two ranges colder..

and i just bought plugs 2 weeks ago.. and they were PFR5G-11 .. the older plugs were PFR5B-11

 

I am pretty sure these are the plugs I got: http://www.ngksparkplugs.com/product...uvs/vpower.asp

I don't see anywhere it says platinum. Should I send them back for some new ones?

 

check this out.. i just checked Courtesy Nissan site..

Their Platinum Plugs are PFR6B-11

Their Non Platinum Plugs are BKR6E-11


I would say you have non-platinum plugs.. send them back and tell them to send you the PFR5G-11
