Bosch Oil Filter - 0451103347

It is recommended to replace this oil filter according to your vehicle manufacturer's service schedule, typically during each oil change. Consult your vehicle's owner's manual for specific intervals.

This filter is compatible with models such as SEAT Toledo 1L 1.9D (1995-1999), VW Sharan (1995-2010) 1.9, and VW Golf (1994-1999) 1.9. Always use a make and model tool to confirm fitment for your specific vehicle.

The anti-return valves prevent oil from draining out of the filter and engine passages when the engine is shut off. This ensures that oil is readily available to lubricate the engine immediately upon startup, reducing wear.

The filter is equipped with a bypass valve that opens at 2.5 bar. If the filter becomes clogged, oil will bypass the filter element, allowing oil to continue flowing to the engine to prevent oil starvation, although it will be unfiltered.

While cross-reference numbers exist, it is strongly advised to use only the specified applications or verify fitment with a dedicated tool. Using an incompatible filter can lead to poor performance, leaks, or engine damage.

The filter has a height of 140 mm, an outer diameter of 86 mm, a gasket outer diameter of 72 mm, and an inner diameter of 63 mm. The thread size is 3/4" 16 UNF.

Ensure the old gasket was fully removed from the engine block. Check that the new filter is tightened correctly (hand-tight plus 3/4 to 1 turn). Inspect the new filter's gasket for damage or defects.

Use a proper oil filter wrench designed for stuck filters. Ensure you are turning the filter counter-clockwise. For extremely stubborn filters, a strap wrench or a filter pliers might be necessary.

Double-check the oil level and ensure it is within the correct range. Verify that the new oil filter was installed correctly and is not bypassing oil. If the issue persists, consult a mechanic.
