Spark Plug gapping

Spark Plug gapping
I have 2000 4runner with 3.4 engine on it. I am gonna change the spark plugs and i bought some Denso 5062 Copper Spark Plugs. The problem is that i dont know how to properly gap them since they have triple electrodes. So does anyone know how to adjust eh gapping on these or should i just install them how they are. Any help will be appreciated.

use a wire gauge not a flat blade. still will have problems, but as far as I know, the best way to check. (i say check because the prior comment is correct that often times plugs are pregapped. but i always like to check)

Most of the triple and quadruple electrode plugs are already gapped. I think you're only suppose to use dual electrodes on the 3.4 though. It says it right on the engine.

don't count on the plugs coming pre gapped. ALWAYS check them. Just the other day I had a set of plugs for a Ford come and one set was good and for the other bank all the ground straps were bent down. some even bent the platinum center electrode. the packaging looked fine.
You never know who is going to drop your parts. ALWAYS CHECK THEM.

No need for off topic ridiculousness. And don't antagonize someone then report his retort, Arnezie.
XPY Digging up old threads is usually not the best idea, but we appreciate any time we get real tech input into the threads that don't have solutions/answers.
Move along, nothing to see here folks

An Advanced Search under Tools (this works much better than the Search box on the main page) of: 3.4 spark plug gap
yields this 2010 thread with the requisite gap information for the dual electrode plugs in post 14 and 15:

My factory dual electrode plugs from Toyota are supposedly gapped, but they aren't.
Use a wire gap tool, not a flat blade....and DON'T forget the anti-seize on the threads!
