Spark plugs NGK 90465 ?

Headhunter.M3 · 03-06-2019, 09:27 PM

Anyone ever tried these spark plugs? https://www.napaonline.com/en/p/NGO90465

New NGK Ruthenium HX made for m3 and m5. NgK states they are better than platinum. I am curious if anyone knows anything about them or has had any experience using them? I am getting ready to change plugs with OEM but noticed these on NGKs website and was curious.
Thank you!

It's just another line of plugs featuring electrodes made of a platinum family metal. It's a typical byproduct in extracting platinum from its ore. It will behave very similar to a platinum plug, last the same amount of time, but they will charge you more for it.

Not true. Just rechecked ngk site. They say both NGK 4471 and 90465 fit.

Maybe they last longer. Some cars have 100k mile plugs now. The gaps on our plugs open up due to electrode wear in less the 30k miles. I doubt any plug offers better performance while the gap remains correct, but some may preserve the gap longer than others.

I just installed the new NGk Ruthenium plugs specifically designed for the E9x M3 and my car(OEM E93) did not like it.

Rough idling

does anyone have any feedback or input?

Remove them and go back to the platinum.

I bought them too, as they're suggested for forced induction and I have Harrop SC. I was strongly told to stick with the standard platinum. I can't return the them. If anyone wants them welcome to them.

Yeah, seems like NGK has made a mistake. I replaced them with the OEM platinum and the car is back to purring like a lion

I'm talking to the distributor to see if they can reimburse me for faulty product

I used those and got multiple misfires immediately. I went back to the stock ones and no problems.
