I recently purchased this item, The image for the product shows 4 pronged spark plugs, but when I got them today and opened the box they are standard looking spark plugs not 4 pronged?Ryan D.Jan 04, 2024
Best Answer:Hi Ryan, I'm glad to assist you. Some spark plugs use multi-ground electrode designs with two or three electrodes surrounding the central one. This provides multiple spark paths for improved ignition efficiency in certain engines. 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, 2WD/4WD, and engine size). The VIN would be helpful.
