Detailed description

Built around Bosch Premium Oil Filter 3972, this engine oil filter is engineered for direct replacement service on many Toyota and Lexus models. The cartridge format, 2.67-inch height, and 2.441-inch outside diameter support the specified OE-style housing fitment, while the 20 micron rating helps trap harmful particles before they circulate through the engine. Bosch 3972 is a practical choice for drivers maintaining Toyota Camry, Toyota Tacoma, Lexus ES350, and Lexus RX350 vehicles with the correct filter housing.

Bosch’s Premium Oil Filter line focuses on filtration efficiency and engine wear protection. This filter uses a blend of filtration materials in the premium line, while the listed filter media here is cellulose paper, paired with a nitrile gasket for sealing performance. Part number 3972 is also referenced for the same application under select cross-reference listings.

What it helps address

• Excess dirt and debris circulating in engine oil

• Reduced filtration performance during routine oil service
• Incorrect filter housing fit when an OE-style cartridge is required
• Oil service intervals that call for a replacement cartridge filter
