350 Mag MPI plug gap?

[OnagaCat]

'03 350 mag MPI SN 0M354722. Bought new plugs but the manual and boat at the lake and I want to gap them here at home. Looked all over the 'net but can't find the gap - anyone know? I think it's .045 but not sure.

+ 1, And hopefully they are already pre gapped spark plugs to 0.060" as these type of spark plugs are easily damaged during the regapping process. So be careful with them. There are youtube like videos on the net of how to correctly gap them if needed.

The plug numbers you can use are as follows,

1, 33- 8M2018369 NGK ITR4A15

2, 33- 884019001 AC 41-993

3, 33- 884019 AC 41-932

I got the AC 41-993 and they were already gapped at 0.060. I did carefully check all 8! Now hopefully the old ones will come out easily.
