Bosch Oil Filter, Spin-On – O 1048:

A Bosch spin-on engine oil filter designed for straightforward replacement during routine oil service. It efficiently separates dirt, soot and abrasive particles from engine oil to protect internal components such as bearings and turbochargers and contribute to smoother engine performance and longer oil life. Its screw-on design makes installation quick and convenient for use on compatible engines.

Bosch Oil Filter, Spin-On – O 1052:

This is another Bosch spin-on oil filter engineered to trap contaminants in circulating engine oil, helping prevent premature engine wear and maintaining performance. Its 3/4″-16 UNF threaded mount and robust construction make it suitable for a variety of light to medium passenger car applications, offering easy filter changes at each service interval.

Bosch Oil Filter, Spin-On – O 1055:

Bosch’s O 1055 is a mid-sized spin-on oil filter that provides efficient oil filtration by capturing abrasive debris and residues before they circulate through the engine. Built with a metric M20×1.5 threaded design, it’s tailored for engines requiring a balance between compact size and adequate filter media area — ideal for many modern petrol and diesel engines.

Bosch Oil Filter, Spin-On – O 1063:

The Bosch O 1063 is a larger spin-on style oil filter with a wide body and M24×1.5 thread, designed to support engines with higher oil flow and contaminant capacity demands. Like other Bosch filters, it separates harmful particles from engine oil to help extend engine component life and maintain smoother operation under varied driving conditions.

Bosch Oil Filter, Spin-On – O 1064:

Bosch’s O 1064 oil filter uses a metric M20×1.5 threaded mount and compact, yet effective filtration design to remove dirt and solids from engine oil. It helps maintain clean oil circulation, which is essential for engine performance and longevity, and is built for easy screw-on replacement during scheduled oil changes.

Bosch Oil Filter, Spin-On – O 1066:

While Bosch O 1066 isn’t listed with a catalogue entry in the Bosch Philippines/Singapore online parts databases, this part is referenced in online retailer listings as a Bosch-branded spin-on oil filter used on certain vehicles (e.g., Nissan Sentra Diesel markets) and is intended for the same primary function — filtering engine oil to protect internal engine components and maintain oil cleanliness during operation. It follows the same spin-on, screw-on design principle as other Bosch oil filters.

General Function of Bosch Spin-On Oil Filters:

Bosch spin-on oil filters are engineered to keep engine oil clean by capturing contaminants such as dirt, metal particles, and soot that accumulate during engine operation. Clean oil is crucial for reducing wear, preventing premature oil aging, and protecting vital engine components such as bearings, camshafts, and turbocharging systems. Their screw-on designs make them easy to install and replace at scheduled oil change intervals for reliable maintenance.
