INTRODUCING THE FL2055
Motorcraft is pleased to announce the availability of the FL2055. This all new oil filter is the service filter for the 2011 model year F-150, 3.5L Ecoboost engine.
All 2011 F-150 trucks equipped with a 3.5L Ecoboost engine were produced with a small diameter (77mm/3 inch) oil filter. The service replacement oil filter, the FL2055, is a larger diameter (94mm/3.75inch) filter. The FL2055 has significantly higher filtration efficiency and capacity than most other oil filters and is designed for added engine protection and long life. For proper engine maintenance, a FL2055 oil filter or an equivalent filter meeting Ford material and design specifications must be used.
If a replacement oil filter is installed that does not meet Ford specifications, engine damage may occur which may not be eligible for warranty coverage. The oil capacity for the 3.5L V6 Ecoboost engine with the FL2055 oil filter is 6.2 quarts (5.9L).
