What is your favorite set of spark plugs for the 98 V6runners?

I'm getting ready to tackle this.

How often should they be changed? and should they be torqued down or is snug good enuff?

 

99 3.4V6, same motor as your 98.

I like the NGK Iridiums BKR5EIX-11 stock # 5464. Change them every 60K miles or so. Yes, torque them to spec. You are going into an aluminum head, stripping would be bad.

Add a dab of copper antisieze compound to the new plug threads. Be sure not to cross thread (again BAD!) by screwing them in by hand with a spark plug socket before attaching the torque wrench.

 

I like just the stock OEM Densos you get at the dealer.
Use a bit of antiseize as Unhappy99 mentioned to make it easier next time.
The plugs have a crush washer on them so tighten until you feel it no longer yields.
I use 2 fingers on the ratchet to ensure I can't put too much strength into tightening them.
Very crude but effective.

 

Great replies fellas, hopefully i can get a couple more replies and make a decision from that.

 

I always change mine with the stock Densos. It comes pre-gapped but it's always good to check the gap before installing it. Like everybody said, don't forget to use anti-sieze. Hope this helps.

I got my truck with about 60k on it. Now I have 80. I wonder if i should change them just to be safe. Perhaps i will.

 

Pull one and check.
If the electrode in the center looks worn, replace em.
