The inside plug twelve cylinder cars had a set of tongs that was used to pull off the spark plug boots when changing the plugs. The plugs were located “inside” the V of the engine between the intake manifolds and were very hard to reach by hand, particularly on a hot racing engine. The early tongs were black. After about 1957 the later tongs were cad-plated. Black Spark Plugs Boot Tongs
Two types of grease guns were used for the 250 series cars. The type with the lathe turned handle was appropriate for the inside plug 250s and most of the earlier cars.

Ferrari used these button-type grease fittings from the very earliest cars until the 275’s. During the production of the 250 series cars some of the pieces purchased from outside suppliers used the normal snap-on type. The sealed tie rod ends are a good example showing that a lot of the later cars used both types of grease fittings. The button type grease fittings were made of brass and plated with a very thin layer of nickel. The nickel finish quickly wore off due to dust and dirt on the road plus the factory recommended 2,500 mile lubrication schedule. The button type grease fittings all used the same dimension for the shaft and head but there was a variety of thread sizes. 5 x 0.8mm: these were used on the very early cars such as the 166s.
