Easily and conveniently change the oil filter to protect the engine and engine components (e.g., the turbocharger) and improve engine performance. Bosch oil filter change boxes separate dirt particles and other residues from the engine oil, thus preventing premature oil aging. No oil loss: seals made of special rubber and corrosion-resistant housing materials. Large filter surface for a high particle retention capacity: provides excellent filter efficiency and reduced flow resistance. Precise construction with coordinated and robust filter components: offers outstanding filter efficiency throughout the entire lifespan. Integrated bypass valve and non-return valve ensure safe engine lubrication even in cold conditions or with a clogged filter.
