Gap should be adjusted from factory.
It is 0.85-0.95

just fitted new plugs, the ones that came out were shot, car has only done 56000 miles thought they supposed to last till 72000, ?

As above the gaps are preset. I took mine out at 72k and they were fine, didnt even have any rust on them.

 

[David Ramsey]

72,000? I didn't think they'd last so long
