So I've read and I guess I will be going with the NGK iridium IX spark plugs per most recommendations on this site. My question is what is the part number for these? I know the same spark plugs can have different heat ranges etc. And I don't want to order the wrong plugs. I don't know much about the car since its my wifes, just trying to get the maintenance done. Also if anyone could tell me the best place to get these for the lowest price i would be greatly appreciative.

 

will these work? I need them for my g35 anyway.

your car calls for NGK PZFR5F 11, platinum tip plugs,, they are about $ 18 each from dealer ,, but you can find them on a part store for around 10-12 dollars each
