BE SURE TO READ MY DESCRIPTION BEFORE COMMENTING. I HAVE 3 PRIOR VIDEOS ON THESE PLUGS AT VARIOUS STAGES WITH DIFFERENT GAPS.

Just followed your plug testing journey, thanks for the videos. I had a similar issue with rockauto got the PSPE version for the ecoboost turbo engines instead of the NA version with the DFE tip. NGK puts a -S at the end of their part number to identify the PSPE square tip version FYI, although as you've seen its not a big deal either way, but as they do make both versions for my car I was able to exchange mine for the DFE tips. I realize it's a little too late for your gap experiment but yeah never gap tighter than min spec for the vehicle. While a tighter gap creates a stronger spark it tends to wear faster from dwell(heat) and less efficient burn at idle/cruising speeds. Generally you want the widest gap you can get away without loosing spark (blowout) during the compression stroke which can cause misifires predominately at higher rpm. The larger gap nets you a longer spark and more surface area for better burn and more complete combustion emissions/economy. I usually gap to the max stated range for the vehicle. However I do check my plugs every oil change still like my dad taught me 30 years ago, I clean them and regap as needed. Since gaps do tend to open over time if you dont check plugs regulary you can go with the tighter gap range for less maintenance.

Oh and another tip, I cleaned spark plugs for years by hand like you until I got me a cheap ultrasonic sink off amazon, was like $40 iirc and its amazing at cleaning all kinds of stuff including spark plugs and makes them look new again. I set them in and run for about 10 minutes and no more cleaning by hand. By the time I'm done changing the oil they are ready to check gap and reinstall. Highly reccommend it!

@@lightblade543 Cool, I was taught the widest gap and make sure outer electrode is 90º to center electrode and maintain crisp sharp edges on the electrode as much as possible (ie don't clean with a tool that dulls the edges. I ultrasonic too, but MicroMesh makes the finish better than factory. So, comparing these NGKs projected square plugs to the OEM Denso double electrode platinums my car originally came with back in 1999, I'm quite certain these NGKs, even when gapped improperly (like in my testing) have a MUCH more optimized flame kernel allowing better combustion (regardless of their gap) as the Denso's perfectly gapped intrusive electrodes which were inhibiting- IKt's safe to say a mis-gapped PSPE is better than a perfectly gapped Denso double electrode.

Thank you for these vids. How many total miles did you run those Ruthenium plugs? My rough math says 80,000ish? Do you think these plugs will last up to 100,000mi like the Laser Iridiums?

@dbfcrell8300 5 ай бұрын

I'm working out the exact mileage I had on those plugs for you. Gimme a day on that so I can check my records. As for the 100,000 mile question, I'd be lying if I said I knew, as I don't know your engine or how you maintain it. I can tell you in my application, the answer is "absolutely". These are the best plugs I've ever used and I plan on never removing these plugs, like ever.

@@dbfcrell8300 I understand. I’ve got a G35 which at 140,000 when I changed them the electrodes were completely eaten away… I’ve changed a Corolla with over 200,000mi on maybe plugs that were either original or at very least 100k and they still had meat on em… both cases were their respective NGK Laser series… just wondering if these held a candle to their durability. Pricing is attractive if they’re even 80% or equal. NGK advertised as most durable, but my question is “to what? Their Iriudium IX?”

dielectric grease makes it harder for it to get a ground. it is oneof the reasons why you arent supposed to add anti seize on the threads.

@dbfcrell8300 11 ай бұрын

The plug's ground is made through the threads. Dielectric isn't used on threads. It's used in the boot only to keep moisture from oxidizing and minimize arcing at the main electrical connection. Anti seize is not supposed to be used because it affects the torque setting. It's made from a metal paste so it's conductive so it doesn't hinder ground. NGK plug threads are treated at the factory so anti-seize is unnecessary.

Looks like your car has wasted spark ignition system . In wasted spark system the polarity of the high voltage ignition pulses is proper (-) on the central electrode and ( +) on the ground electrode and opposite on the other spark plug in the pair ( on the same ignition coil ) . When the polarity is proper most of the erosion happens on the central electrode ( ruthenium ) and the ground electrode ( platinum) is less affected , but when the polarity is reversed the erosion is stronger on the ground electrode and since it’s platinum ( less tougher than ruthenium) it erodes faster . This IMO is the main reason why 2 of your plugs looks almost OK and the other two almost lost their projected tips . 78K miles isn’t small mileage but not for rare earth metals electrodes plugs even with wasted spark ignition system . The engine firing order is 1-3-4-2 ( they are paired 1&4 and 2&3) so the plugs on cyl #1 and cyl#2 are with almost intact ground electrodes and cyl#3 and cyl#4 completely worn, so the last ones have to be working with reversed polarity . What I can suggest you for extending their life time is to rotate them . This is specific only for the wasted spark ignition systems !( two coils ( with two high voltage terminals each) per 4 cylinder engine !

Ok, does my running them all at .032" gap for 17k miles have anything to do the significant erosion? They were perfect up til that part of my test. They're supposed to be gapped at .044" (which my new ones are) but I was experimenting with decreased gaps for several mos with the plugs in this video. IOW, if I leave my new Rutheniums at the correct gap, will rotation still be necessary?

@@dbfcrell8300 The smaller gap increase the spark current , so probably yes but there is something wrong with the material of this projected tips . So better rotate the plugs ( since you will put the same ones ) on every second oil change and don’t clean them !
