These will also fit the 1972 U.S. version 350SL with the 4.5 engine. Just make sure of the correct color. WARNING: MAKE CERTAIN your current injectors are blue/green at the top.

Watch for the video below for a full description of the kit with up-close details and testing results. PLEASE NOTE: These are the same injectors used on 1974 and 1975 engines, but the seals included do not work. If you have the latter engine with the nylon insert and small green o-ring, you are welcome to buy these injectors, but we do not carry those seals. The nylon sleeves are NLA, and the small green o-rings are still available as of May 2024. See our listing for Late 1974 and 1975 4.5 injectors in the related products below.

Product Details
This month's bonus: We will include a set of modern plug in wire connectors at NO CHARGE with your order now. You do not need to use these plugs. The original plugs will work if they are not damaged. You would need to splice these into your wiring with butt connectors ( either wire can go to either side of the injector plug. There is no polarity). So it will be your choice whether or not to use them. They are free!
