At about the time of the introduction of the new four passenger 250 GTEs F.I.S.P.A began supplying the air cleaner assemblies with a decal to replace the metal tags that had been used previously. The timing chain covers were painted with the black wrinkle finish to match the valve covers. These decals were used on the air cleaners and a change was made to the three-ear type wing nuts. These decals should be trimmed carefully and applied with a few drops of soapy water to the top of the air cleaner towards the front of the car. 250 Outside plug F.I.S.P.A. air cleaner decal.
