These will fit all 1977 to 1991 4.5, 3.8, 5.0 and 5.6-liter V8 engines. Do not use NGK, Platinum or any other kind of "special" spark plug. You will be sorry. Use only these Bosch Super plugs. These are the best you can buy that are readily available regardless of the price. PLEASE NOTE: These performance Bosch spark plugs have an aluminum end cap that does screw off. You will receive the plugs with the end cap installed. Check your current spark plugs and spark plug wires before installing the new plugs. If your spark plug ends just show a tip with small threads, then you will need to take a pair of pliers and twist off the aluminum end caps before installing the new plugs in your V8 engine. These will really make the engine in your R107 sing. As seen on Cherry. CLICK HERE to watch the full video series on Kent’s R107 rolling restoration.
