Bosch Oil Filter - 3/4 UNF - 93mm x 76mm

Its primary advantage is its compact design and high-quality filtration, making it ideal for engines with limited space, such as those using remote filter heads or oil cooler sandwich plates.

This refers to the thread size and pitch of the filter's connection point. It's a specific standard that must match the port on your remote filter head or sandwich plate.

It's recommended to replace the oil filter at every oil change, or according to the interval specified by your vehicle manufacturer or the supplier of your remote filter head/sandwich plate.

The anti-return valve prevents engine oil from draining back out of the filter and oil lines when the engine is shut off. This ensures faster oil circulation and lubrication upon the next startup, reducing engine wear.

If the filter media becomes too restricted, the 2.5 bar bypass valve will open, allowing oil to bypass the filter media and continue to lubricate the engine. While this ensures lubrication, it means unfiltered oil is circulating.

This filter is specifically designed for remote filter heads or oil cooler sandwich plates with a 3/4 UNF thread. It is generally not a direct replacement for standard spin-on filters that screw directly onto the engine block, unless you are adapting your system.

Ensure the filter gasket is properly seated and lubricated. Double-check that the filter is screwed on tightly enough (but do not overtighten). Verify that the mounting surface on the engine or adapter is clean and flat.

Confirm you have the correct 3/4 UNF thread size. Ensure there are no cross-threads or damage to the filter's thread or the mounting stud/port.

Verify the filter is correctly installed and the oil level is adequate. Check that the anti-return valve is functioning correctly and not stuck. Ensure the bypass valve is not stuck open.
