The I just did this little drawing to help.
The arrow is pointing at the gap.
The gap should be .060" of 1 inch (would be measured as 1.000") according to the factory for optimal performance on a stock original 3800 engine.
You can get a spark plug gapper at any parts store, Wal-Mart, K-Mart, Target, etc..... -the cheap one'* for the keyring can be bought for under $1 sometimes and they prove to be very helpful at the track, or anytime you are putting new plugs in.
