What's your experience on the longevity of your iridum plugs? How often do you re-gap them?
Thanks.

 

Searching the forum some have 40K miles on them, anybody who has more?

 

I only have 26,000 miles on my iridium plugs. I have never taken them out and everything seems to be ok, no idle problems or studdering. Though, I did have to replace the coil pack 2,000 miles ago. That was entirely unrelated.
