I have a 2013 +pp, GH tune n intercooler,  stock thermo, stock airbox drop in dry panel filter. I have sp-534 plugs at stock gap. Plugs have 35,000 miles. I was getting ready to change them and wanted to see the best plug for my car. I live in nj. I looked on rock auto. They have copper, platinum,  iridium and now for 1 buck more then iridium these new plugs.......
Ruthenium HX
NGK Spark Plugs is introducing the latest technology in high ignitability spark plugs to the automotive aftermarket: NGK Ruthenium HX. Today's efficient engine designs create more power while using less fuel and this has shortened the life of traditional Iridium and Platinum spark plugs. In response, NGK's patented Ruthenium technology is used for maximum durability and performance in newer engines where efficiency is demanded.

Features & Benefits:
DFE (double fine electrode) and PSPE (projected square platinum electrode) tip designs. DFE maximizes ignitability while reducing emissions for low heat (non-turbo) engines, and PSPE provides the best ignitability and service life for high heat (turbo and supercharged) engines.
Superior oxidation resistance and enhanced blistering/anti-peeling to provide the most optimal durability at high temperatures in various driving conditions.
Advanced high-ignitability technology that provides more complete fuel burn than other precious metal spark plugs, resulting in quicker throttle response, smoother idle, and better cold starts.
Anyone heard of this metal or these plugs?
Are the sp-580 the new number for the sp-534 still the go to plug. What would my gap be for my po particular combo be?
Sp542@.028, windstorm CAI, MSD coils, AO GH TUNE, GH intercooler, All Amsoil, General Gmax-rs summer tires, +PP, PP PADS,EDC rotors, Colinite 476s wax, used PPE DPs, Resonator | 3rd Cat Delete with custom X pipe, Dicunzolo Gen2 Trans Mounts|, 3 bar, stock thermostat,  TRACY LEWIS DESIGNED Team RXP, the Original oil separator.

Yes the sp580 is the updated part.  Same gap 0.030.

If tuned:  Take note of the strategy code as you return to stock (including 3 bar MAP to 2 bar MAP) -> take car in & get it serviced -> check strategy code when you get car back -> have tuner update your tune if the strategy code has changed -> reload tune -> ENJOY!

Interesting find.

Here's something on working with the metals.

https://www.mgsrefining.com/blog/2015/10/01/Ruthenium-vs-Iridium-in-Platinum-Alloys

And here's something on the scientific properties.

https://www.google.com/amp/s/metals.comparenature.com/en/ruthenium-vs-iridium/comparison-61-33-0/amp

It SOINDS like the gap of the ruthenium plugs won't increase over time as much as the iridium plugs will.  So that might be the gain from these plugs. However, if you change your plugs every 20 or 30, 000 miles, the plug gap increase might not be an issue for you.

Look at this video of a tuned SHO with SP534's and watch preignition.  Now watch how it isnt an issue with SP542's.  This video is the reason why I will be ditching my SP534 that only have 3k miles on them to the SP542.

There are different levels at which different spark plugs are called for.  So, dont throw away the old plugs until you see quantifiable benefits with the new ones.

Which plugs are the stock plugs ? 534s? Or 542? I forget . I put stock plugs in at .028

Sp534 I believe...or I actually thought this to be an upgrade per LMS' site.  They list it as an upgraded plug.  And SP542 is a step colder than SP534.  So I don't believe either are stock...not 100% on that

Sp534 is stock, replacing the sp528 that had issues with cracked insulators.  Sp542s are "upgrades".

Well I'll be getting out the spark plug socket again . Brad was saying my symptoms after flashing the E30 tune were abnormal and something doesn't seem right . That may be symptoms of LSPI , I still time to time feel slight hesitation on light take off around town etc

SP534's sold as an upgrade?  For nothing other than a precision gap?  Hence the confusion on whether they are stock or not.

I do not see the word "upgrade" in the pic above.  Because plugs from factory arent always matched evenly, becaused boosted applications are more sensitive to plug gap, and because gapping them properly is a challenge with the tiny center electrodes, LME provides the service to eliminate the headache for the customer.

True but they are a performance shop selling upgrades not stock replacement parts.  For the beginner such as myself I as well as many others would find it suggestive to say the very least of a upgraded spark plug when it is only a stock plug that has been precision gapped.  For a beginner as well gapping a plug is entry level or 1 wrench in difficulty...so to buy stock plugs and pay nearly double bc they are "precision gapped" seems ridiculous and are probably out of gap during shipping for all we know.  Just my opinion.  I find it to be misleading and all the times I boasted about my performance pack I bought....intake, thermostat, plugs and tune....if I only knew I was boasting about replacing it stock plugs with stock plugs...

The only Spark Plugs recommended Gapped @ 0.028 are the NGK (6510) LTR7IX-11 IIRC! The rest line of the NGK Re-branded Motorcrafts are @ 0.030 Gap size. Z

Most tuners are recommending even with the 534s and 542s to run .028 to .30 I'm going to run .028 with a little wiggle room for the gap to expand slightly over time , very common
