Why choice the W67/81 OIL filter?
The W67/81 is a spin - on filter with an anti - return valve. The anti - return valve can prevent the engine oil from flowing back to the oil pan after the engine is turned off, which reduces the dry - grinding time of the engine when it is started again and protects the engine. In addition, its structure design is reasonable, which is convenient for installation and disassembly, and is also conducive to the smooth flow of engine oil during the filtration process.
