How to Maintain a BMW 5 Series?

Correct installation of the air filter can reduce wear on components such as cylinders, pistons, and piston rings. Proper installation of the oil filter prevents impurities from mixing into the engine oil during the operation of the internal combustion engine, avoiding wear on moving parts and clogging of oil passages. Replace when necessary, and clean the fuel injectors without disassembly. Check if the idle valve is excessively dirty and clean it if necessary.
