the default gap is 1.1mm should i change to 0.8 or not and many thx

The right answer has to come from NGK. It's their job to reply to any query from their customers. It's their stuff, their technology, their marketing.

 

As a side note, In real life "Enhanced Ignitability" and "Trivalent Metal Plating" means BS. No extra power, no lower consumption. No measurable improvement. A waste of money.
