Bosch 72226WS Engine Oil Filter

Bosch Workshop Oil Filter 72226WS

The Bosch Workshop Oil Filter 72226WS is a spin-on engine oil filter built for a wide range of Honda, Acura, Nissan, and Mitsubishi applications. It uses cellulose paper media, a nitrile gasket, and internal valves to support steady oil flow and engine protection during routine service.

With a 30 micron rating, anti-drain back valve, and bypass relief valve, this Bosch oil filter is engineered to capture fine contaminants while helping maintain oil pressure at startup. It is a practical choice for drivers looking for a direct-fit engine oil filter for many Honda Civic, Honda Accord, Acura MDX, and Nissan Frontier applications.

Product Details

Bosch Workshop Oil Filters are part of the Bosch Workshop Oil Filter line, focused on everyday service parts for import vehicles. Part number 72226WS is built around cellulose paper filtration and a compact spin-on format, making it suitable for many late-model and older Asian vehicles that use an M20x1.5 oil filter connection.

This part cross-references common aftermarket applications such as Fram PH7317 and Purolator L14610 for the same application.
