Product Details

Bosch Premium Oil Filters are built to maintain engine performance by filtering out contaminants that can accelerate wear. The Bosch Premium Oil Filter 3401 uses cellulose paper media and an anti-drain back valve to support cleaner oil delivery at startup, while the bypass relief valve helps maintain circulation if the filter becomes restricted. This makes it a practical choice for drivers looking for a Bosch 3401 oil filter replacement with OE-style dimensions and thread specification.
