I know, I know. Another sparkplug thread. I searched, read the manual and called Toyota parts but I'm still confused. Through research I've found that some 3.4 engines came from the factory with one side denso one side ngk. When I called Toyota the guy told me "Two different types of spark plugs, That's a whopper of a story." lol Silly me thinking people at the dealership would actually know what they're talking about...

1. Do I stick with 3 denso/3 ngk?
2. Do I gap them or just leave them to what the are at out of the box?
3. Platinum? Copper? Uranium? (yes that last one was a joke.)

Thank you for your time.

 

Its so you can tell if your plugs have been changed before. Thats pretty much it. Ide go with NGK's just go to napa and get the dual electroid and no you dont have to gap them
