98 runner 3.4 plugs
 

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

I'm getting ready to tackle this. :nerd:

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. :D

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

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.
