Questo tipo di filtro, noto come filtro spin-on, è costituito da un elemento alloggiato in un involucro filettato in acciaio, che consente l'avvitamento diretto al corpo motore. Il filtro spin-on vanta notevoli vantaggi, tra cui la sua struttura robusta, che presenta un'elevata resistenza ai danni, e la sua semplicità di sostituzione. Quando è il momento di sostituire il filtro olio spin-on, la procedura è pressoché semplice, riducendo al minimo il rischio di introdurre impurità nel sistema di lubrificazione del motore. Questa progettazione non solo garantisce una filtrazione efficiente, ma migliora anche l'esperienza di manutenzione complessiva, contribuendo alla longevità e alle prestazioni del motore.

These filters are installed within sealed housings that are integrated with the engine. Typically, these housings are equipped with all the necessary valves for ensuring proper filter AP 133/9 functionality within the engine oil system, along with components that secure the filter element in place to maintain its tight seal within the housing. Modern oil filter elements are crafted without the inclusion of metal parts. Instead, the bottom caps and cores of these filters are constructed using advanced plastics. This transition away from metal components not only benefits the environment but also facilitates easier disposal processes.

Contemporary passenger cars, especially those equipped with numerous additional systems such as air conditioning, have limited space under the hood. As a result, manufacturers are increasingly opting for different types of air filters that better suit the new air intake systems. Nevertheless, in high-capacity luxury vehicles, where performance and precision are crucial, circular air filters with intricate structures may still be used.
