Product Details and Specifications

The Bosch Premium Oil Filter 3520 features a spin-on design with a 1-16 thread size connection, making it compatible with specific Dodge Ram and Dodge truck models. The filter media is made from cellulose paper, which provides a micron rating of 20, effectively filtering out fine particles from engine oil. The filter measures approximately 6.87 inches in height and 3.661 inches in outside diameter, fitting securely in the designated filter housing. The nitrile gasket ensures a tight seal to prevent leaks, while the filter's burst pressure rating of 200 PSI indicates its durability under high-pressure conditions. This filter does not include an anti-drain back valve or bypass relief valve, which is typical for certain engine configurations.

Installation Notes and Tips

When installing the Bosch Premium Oil Filter 3520, ensure the engine is cool to avoid burns. Apply a thin layer of clean engine oil to the nitrile gasket before installation to improve sealing and ease removal during the next service. Tighten the filter according to manufacturer torque specifications, typically hand-tight plus a quarter turn, to avoid over-tightening. Since this filter does not have an anti-drain back valve, it is important to check oil levels after installation and initial engine start-up.
