I am sure we have some tech guys around here that can help me out..
I have searched all over and cannot get a good answer on how to gap a spark plug that has 2 grouding electrodes.
I have a 2003 Tacoma 3.4 V6
I bought NGK plugs for it

Help and thanks!

i work at carquest auto parts. don't try to adjust gap, it will ruin them plugs. they come pre set from NGK. if one side is smashed in, you need to return it to the place you bought it, they will give you a new one for free.

my computer says it should be gapped to .044 but i can't tell you where the measure from.

that is what i was told also, grab one off of the shelf, to me it looks like it is .022 on each side of the electrode....

dual ground plugs don't make a bit of difference in horse power or performance vs a standard single ground plug. electricity ALWAYS takes the path of least resistance so the spark will travel to only one ground. The dual ground could have the same gap on both sides but the spark can still only travel to a singe ground at a time. usually one ground is just a tad closer to the electrode so the spark will always travel to that one. if that makes any sense.........

first of all, who says anything about power?? we where talking about the gap of a certan kinda spark plug.


second, i want you to try to install a single electrode plug in a tacoma,or a volkswagen for that matter, let me how that turns out for ya!!

and third, it's a regular resistor spark plug, yep you heard me right a resistor just like you pappys truck from the '60s used. the reason for the dual electrode is so they can get 100k out of a resistor plug.

it is not a dual electrode plug. it is a dual-ground, single electrode plug.

this type of plug fires twice as often and maintains the typical change interval for a typical plug. toyota came up with a special ignition system in the early 90's that uses this type of plug. i was just saying the spark doesn't travel at the same time between the two grounding posts.

i know you were talking about the gap, looking at the pic just reminded me of some experiments we did on different plugs in an electrical engineering lab in college years ago. wasn't trying to get ur panties in a wad. sorry!!!!!
