    Who gaps their dual electrode plugs before install? There seems to be a lack of internet content showing this, or how to do this...

    I do/did. Just put six new NGKs in and like the peace of mind of KNOWING they were right. Only one needed a minor nudge.

    So I just did the plugs and wires. Also read more and researched a ton on the whole gaping dual probe plugs, specifically the NGKs. I read on some other forums that the gap is not measured at the tip to probe like a single setup and some have claimed to talk to NGK reps and confirm this. I wanted to know for sure so I emailed them yesterday, got a quick reply. A bit vague, but I'll ask for more clarification. Emails:

    ME:

    Hello, I was writing to inquire about the BKR5EKB-11 spark plug. I was curious as to how to check/adjust the gap on these, if necessary at all. I've read lots of conflicting information on the subject and wanted to just come to the source. Is the gap measured at the tip or down around the insulator? I've also read that the 2 tips should be .022 for a total of .044 for this application. Any information and advice would be greatly appreciated. Thanks in advance for your time and assistance.

    NGK:

    Hello,


    Thank you for your inquiry. Since the dual ground plugs are only intended for certain applications, they come pre-gapped. You cannot adjust the gap because they are laser measured from the exact center of the center electrode. And because it does not spark straight up and down like traditional plugs, they are measured differently.


    Not sure if I'll get much more out of them, but hope this helps. Oh and picture because pictures are always required...

    At 80k miles on a 2000 Taco, just did mine with NGK wires and Denso dual tip cheap plugs (OEM) from Amazon. checked the gap with the wire gap tool; the gaps were all, consistently, very close to .044 so i slapped em in. Super easy, idles smoother, very afforadble. Cleaned he MAF. should have replaced the PCV valve while i was in there, its like a $5 part.

    Didn't even check mine. Just installed. Runs smoothly. Didn't do maf or pcv either. And still trying to isolate the p0302 code. Coil swap is next.

    A gap is a gap man, it's the distance a spark has to jump from the electrode to the prong. check the gap on both sides of the electrode. It fires randomly between the two depending on conditions and functions the same as a single prong plug other than spreading out the wear. These motors are designed with long maintenance intervals in mind so these plugs make it possible to hit 100k before a change.

    Anyway the gap depends on the size of the prong, or number of prongs.

    Same exact thing happened to me as OP. Changed carrier bearing still had vibes. Realized vibes were still there when in drive with brake held and engine loaded. Pulled plugs and they were shot. I got the replacement plugs from Toyota 5.99 each and pre gasped. The plugs I got from orileys looked much different.

    Also was advised by Toyota tech not to put grease on the plug threads

    As already mentioned, at least with NGK / Denso plugs there is no need to apply anti seize to their threads as the nickle coating will act as a natural lubricant. So good move!

    Anyone know where I can get 3 of the 10mm bolts for the coils at? Changed plugs and wires today but 2 of 3 bolts were rusted and in the trash now...

    Truck was much smoother after replacing these. Not sure if ever replaced.

    I got around to replacing my plugs & wires at 195k. I bought this truck with 163k & I am not sure if they have ever been replaced. My truck developed a severe drive line vibration which caused me to replace them sooner than later. Each of the 6 replaced plugs were between .052-.058
