This socket works on the new Mercedes AMG engines. It is not a good fit for the Ford F150 engine. Other applications include Nissan and other Japanese auto and motorcycles. Check your owners manual for recommedatins.

Note: We also stock a 16m or 5/8 magnetic spark plug socket by KTC. See pull down menu for price.

This plug has a slim profile(matches the OEM product dimension) and has a strong magnet to grip those little spark plugs. It will also fit in the manifold of those Japanese rice rocket motorcycles that use this size plug.
