you shouldnt have to put anti-seize on the plugs unless you planning on running them for 100,000+ miles, which I wouldnt recommand.

Aren't the plugs made to last 100K miles? Seems like the owners manual mentions changing them at 103K but I could be wrong.

My factory plugs exceeded the service limit gap of .051" when the car was at 55k miles, they were well over that gap as the center electrode wore down /eroded. You can try to run them for 100k miles but I would check them well before that, and on a regular basis, every engine seems to be slightly different. I would have hated to see my plugs at 100k miles.

I think 40-60K miles is a good time to check/replace the plugs. If the plugs aren't bad, you might find a tube seal (O-ring) leak to fix.

To bad I didn't read the fine print from NGK before I put the last set of plugs (8) in my Tundra with anti-seize! No harm I guess.
