So, I ordered platinum NGK plugs from infinitipartsusa.com. They had a great sale going - basically half price. Just a bit over $5 instead of over $11 a piece.

I specificed my model and what I received were PFR5G-11 plugs. Just wondering if these are the rights ones. I've seen PLFR5A-11 in the owners manual as the recommended plug.

Any comments? Do I need to return these and ask for the proper ones or will these do?

Thanks for any help.

Nope, those ones are fine to install.

 

S.b.f.!!!!!!!

 

I was looking on NGK's site because I had just recently purchased iridiums and I dont see the part number that you received referenced for a 3.5 VQ DE. The only other platnium plug is the G plats and they have a different part number.

 

I noticed the same.

 

That part number does not show any reference for any 3.5 VQ equipped Infiniti or Nissan vehicle. I personally would not use a part was not that specifically referenced. If it was the same plug then it would have the same part number. I would give them a buzz just to clarify.
