Detailed Product Description

The Bosch Premium Oil Filter 3401 is part of Bosch's Premium Oil Filter line, which focuses on delivering dependable filtration performance for various engine types. This filter uses cellulose paper as its filtering material, which effectively traps contaminants while allowing optimal oil flow. The spin-on design with a standard M20x1.5-6h thread size ensures compatibility with multiple vehicle models such as the Chevrolet Corvette, Ford Ranger, Jeep Cherokee, and Mazda B2200.

Equipped with an anti-drain back valve, the filter prevents oil from draining out when the engine is off, reducing wear during startup. The bypass relief valve activates between 8 and 16 PSI to maintain oil circulation even if the filter becomes clogged. With a burst pressure rating of 200 PSI, the filter maintains structural integrity under high-pressure conditions. The nitrile gasket provides a reliable seal to prevent leaks.
