No need to gap. just put them in as they are. They are pre gapped from the factory.

Anywhere from .050 to .060 you will be fine. Check them out of the box, I have seen them come out as low as .020 from the box, they are pre gapped at .050 but mistakes happen, plugs fall, etc.

Ha, i'd definitly check the plugs before putting them in. I had a set that were so inconsistent. Some even in the .070's.

Some go .060 (stock), others go .050. I'd just take the medium of .055.
