These will fit all 1970 to 1975 3.5 and 4.5 V8 engines with D-Jetronic fuel injection (electronic). Do not use off-brand, platinum or any other "special" spark plug. They will try to sell you newer-style plugs at the auto parts store. You will be sorry. Use only these Bosch Super plugs. The best you can buy that are readily available for 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.
