I have probably 7K miles on my existing plugs... how often are you guys that are running really advanced timing changing out your plugs?
I'm gonna pull em and check their conditions, just thought I would ask...
I'm Running a bit Rich so every 10K-12K for some reassurance. Z
Yea just did a quick check of bank 2... all looks good for the most part.. there is some brownish spots on the insulator at the tip... not sure what that is from..
The plug s****ing itself when you smash the WaWa pedal.

Did you happen to check the Gaps on them?. Z
Yea.. all still .030.
Still looking for an answer. Found this vague tidbit from NGK
DOES IGNITION TIMING AFFECT A SPARK PLUG'S TEMPERATURE?
A: Yes, ignition timing directly affects the firing end temperature of the spark plug. Advancing the ignition timing prolongs the time to compress the burning gases. The pre-ignition temperature also elevates gradually, since the pressure and temperature of the combustible mixture is low before ignition. Advancing your timing elevates firing end temperatures.
Insight from HOT ROD, the oracle ;)

Checked bank 1... all look good, all gapped still at .030....
All have the burned brown spot by the strap on the insulator...
Unfortunately I have used three different tuners with multiple upgrades along the way since replacing them originally for Unleashed tune... so unsure which tune might have caused the burns on the insulator...
Might just thrown in a new set... autozone has them for 6.99 a pop.. plus some kind of coupon...
Since you are now running methanol worth asking ajp if colder plugs are of any benefit.
New set of SP-534's... purring nice and smooth... I guess all the tuning changes and datalogging over the past 7K miles put a hurting on the older plugs...
So even with the perfect gap on the older plugs, the new plugs made a noticeable difference? Interesting.

It would appear so... or it's just placebo... but I was having what I perceived as a miss at the higher RPMs when I was hammering it... seems to have gone away now...
Or since my engine bay ate one of my original craftsman(made in USA) 8mm deep well sockets it damn well better be running better...

I am less surprised. The tighter and more dialed in any tune becomes the more dependent it becomes overall on each component and each variable. While the old plugs were fine at one time, the continued increasing tighter tolerances made the slightly used plugs play a great role in ignition variance.
I had this once I did a small build on my vq35de, after nismo cams, berks, nvidia exhaust and intake porting and a dyno tuned Orsis variant I found the old plugs ran like crap after about 15-ish-k miles, idled rough with tiny little misfires i could feel in the wheel. ran fine under load but in light loads i could sense a coarseness that was only corrected by gapping new plugs and jamming them in.

Yes
Done! Glad she's purring like a Bobcat once again. Z :)
26+ WOT timing @ 24K original plugs.

Yea, not sure if one of the plugs were faulty or not... seemed early to me as well...

I had them checked about 20K and they were perfect.
I checked them the other day, all were still at .030 according to my feeler. However, the ground strap looked pretty rough and the insulator was scorched a bit on each one.
Unfortunately I don't know which tune could have causing it to run that hot as I have had 3 tuners work on it....
I rarely have KR so I am unsure.... gonna keep Brads tune on this one and check them at 3K to see if they are still getting scorched.
None the less, the miss is gone so something was not happy.
So are you guys running the E30, E50, E85 etc. etc. tunes doing better than the guys running 92-93 etc. etc. octane gasoline tunes on plug life with ethanol or not?

Yes
So are the SP-534 the recommended Go To plug for tuning if you want to replace your Originals? I have 30K on my 2015 and will be tuning with AJP in a month or so. Just doing Plugs, 3Bar, K/N Filter, Thermostat.

I was running E blends which have a cooler charge... same with my meth setup... both tunes allow me to crank out more power than 93 octane by adding more boost/timing.. which can eat plugs.. especially the timing.

Yes, SP-534 gapped at .028 - .030 is recommended.

Awesome.
Thanks for the help.
