Plug gap

[Rum Runner]

Anybody have a preference on the spark plug gap NGK's,the bible says 32 or 35 thou. 4.0HC ?.

[GreenV8S]

35 thou / 0.9mm or there abouts - if you're getting NGKs they will probably come pre-gapped to that anyway.

[Big Ashy]

Always use NGK mysef, but don`t rely on the pre-gap, I have found some to be way out. 35 thou for me

[itstvr]

The Service Manual and NGK themselves say 0.8mm
