IMO ...The NGK V-Power BKR7E is a great stock/copper based plug for the NA S.Boosted I would go +1.For older/higher mileage cars that burn some oil I would go -1 range.

stock gap is 0.044" Thats what the -11 in the ngk part number means
I usually run with a heat range colder than stock. I was getting some detonation with 7 heat range plugs, and the heat was way to far up the ground strap. 8's were perfect.
bkr8e or bkr8eix work really well.
