hello guys , so im doing a spark plug change on my 2015 Infiniti Q50 with about 64k miles im currently tuned. So I was wondering if I can run the NGK Ruthenium HX Spark Plug (91784) on it. I found them for under $12 from auto zone and other websites , I was wondering if the vq37 can take Ruthenium plugs over the Iridum stock ones. OEM ones are about $19-$22.

I figured since im tuned I was gonna get stronger plugs plus its cheaper.

You can run the ruthenium he as I got them when they first came out but the iridium were still better I think overall and even though the ruthenium are touted be just as good. There is a huge price difference between the NGK DF8H-11B which is what I run in my hybrid.
