Spark Plugs options

weihan · 07-20-2020, 09:36 PM

Has anyone ever tried the new NGK Ruthenium spark plugs (LKAR8BHX)? They're going for $68 for a set of 6 over at Zspeed. Searched the forum and only found 2 posts about it and nothing much else on the interwebs on how they perform on VQ platform.

I'm deciding between the NGK Ruthenium and the Iridiums DF8H-11B. Have some trust issues with Denso.

Stock 370z with roughly 60k miles on the clock.

What's the selling point of Ruthenium?

Have about 1.5k miles on these plugs since I put them in. Car runs great, no issues or complaints so far. I personally trust NGK above most other plug manufacturers, just personal preference having used them for years in many different vehicles. To the OP, check Rockauto.com or maybe even amazon or ebay. They can be found much cheaper if you do a little searching.

Advertised as more robust and longer lasting tip as compared to platinum and iridium and fits a wider range of AFR without triggering knock that easily. *If any of that makes sense*

Yup, I ordered form rockauto just to try it out. If it fails then I'll just order a set of iridium to replace it. And thanks for the feedback. Looking forward to see what wonders it does. Haha
