the spark plug gap is .054, but the gap between the spark plug and your car should be the distance from you car to the parts store. take 'em back. this is an old topic, but too many people have tried bosch with less than stellar results (rough idle, poor mileage, poor performance). the heat range they function in is wrong. get some autolites, double platinum preferred, or just go get another set of motorcrafts.
r u sure that price is for double plats, micro? sounds like the price on a set of regular plugs, maybe single platinums. generally, i see regular autolites going for about $1 a piece, single platinums at about $2, and double platinums for about $4.
