These will fit all 1976 to 1991 4.5, 3.8, 5.0 and 5.6-liter V8 engines with Bosch C.I.S fuel injection. PLEASE NOTE: These 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 W116, W126 and R107 sing. As seen on Cherry. CLICK HERE to watch the full video series on Kent’s R107 rolling restoration.
