I have a 2014 Maxima SV, with 150k. I need to do the plugs and coils on, so I bought the Denso FXE22HR11, new plugs from a local auto parts store. They were pre Gapped at like .30 - .35.

Seems Nissan says Denso gap should be .043-.055. So I Gaped them at .40 to split hairs. What is the correct Gap? This is very confusing. Normally the Denso's are already pre Gaped for the car> Anyone please??????? Thanks.

Gap is 0,043", see page MA-26:

Gap usually widens with mucho mileage too ...........they don't come closer together at all during their "run" inside your heads/engine.
That .043" , the lower posted , Vstar spec sounds good yeah

The gap " Spreads Like the Covid " see here....see here
