Best Answer:Hi Reginald, I'm glad to assist you. All of our direct-fit spark plugs are pre-gapped already. Still, for us to check carefully and be accurate on the part you need, please provide the complete details of your vehicle (year, make, model, submodel, and engine size). The VIN would be helpful.
