Haynes says "0.0028 - 0.0031 inch" for NGK BPR6EKN or equivalent. I gap' mine to 28-30 also.

My buddy is pushing 25psi of boost plug gap what ever they were in the box close enough for us, point is no misfires. you ever think that the misfire is most likely caused else where, for say wires, or the plugs you have, also maybe that bpr7es may have a bit to high of a self cleaning temp for your application

Check for burn marks on the sides of boots
